The answer is the field vector is perpendicular to the surface.
The electric field's angle with the equipotential surface is always 90 degree. The electric field is always perpendicular to the equipotential surface.
What is electric field?
- The electric field is formally defined as a vector field associated with each location in space, the force per unit charge exerted on a positive test charge at rest at that place.
- The electric charge or time-varying magnetic fields create the electric field. At the atomic level, the electric field is responsible for the attractive forces that hold the atomic nucleus and electrons together.
- The normal vector to a surface, often known as the "normal," is a vector that is perpendicular to the surface at a particular position. When considering normals on closed surfaces, the inward-pointing normal (pointing towards the surface's interior) and outward-pointing normal are commonly differentiated.

- The equivalent capacitance between point a and b is 5.87μf.
- The charge at 20μf is 93.92 μC.
- The charge at 6μf is 67.8 μC.
- The charge at C and 3μf is 26.12 μC.
<h3>
Sum of capacitance of C and 3μF</h3>
The sum of the capacitance is calculated as follows;
1/Ct = 1/C + 1/3
1/Ct = 1/10μf + 1/3μf
1/Ct = (3μf + 10μf)/30μf²
1/Ct = 13μf/30μf²
Ct = 30μf²/13μf
Ct = 2.31μf
<h3>Total capacitance in parallel arrangement</h3>
The total capacitance in parallel arrangement is calculated as follows;
Ct = 2.31μf + 6μf = 8.31μf
<h3>Equivalent capacitance between point a and b</h3>
1/Ct = 1/8.31μf + 1/20μf
1/Ct = 0.1703
Ct = 5.87μf
<h3>Charge flowing in each capacitor</h3>
Maximum voltage is delivered in 20μf, q = CV
<u>charge for 20μf:</u>
q = (5.87 x 16)μC
q = 93.92 μC
<h3>Equivalent capacitance for C, 3μf and 6μf</h3>
Ct = 2.31μf + 6μf = 8.31uf
<u>charge for 6μf:</u>
q = (6/8.31) x 93.92μC
q = 67.8μC
<h3>Total charge for C and 3μf</h3>
q = 93.92μC - 67.8μC = 26.12 μC
charge for C = charge 3μf = 26.12 μC

let the ron and hermoine apply force along the horizontal direction . let ron pulls in left direction. and hermoine pulls towards right
lets assume that the left direction is taken as negative and right direction as positive.
F = force applied by ron towards left
F' = force applied by hermoine towards right
a = acceleration of the book
m = mass of book
force equation for the book is given as
- F + F' = ma
Given that : F = F'
hence
- F' + F' = ma
0 = ma
a = 0 m/s²
since the book was initially at rest and the acceleration comes out to be zero, hence the book will not move.
so correct choice is
D) The book will not move
c A ray of light is divided into its constituent colors by the first prism (left), and the resulting bundle of colred rays is reconstituted into white light by the second. Our modern understanding of light and color begins with Isaac Newton (1642-1726) and a series of experiments that he publishes in 1672.

Answer:
a)The temperature of the gas in increased by four times its original value.
Explanation:
For a fixed amount of a gas, the ideal gas equation can be written as follows:
where
p is the gas pressure
V is the gas volume
T is the gas temperature (in Kelvins)
For a gas under transformation, the equation can also be rewritten as
where the labels 1,2 refer to the initial and final conditions of the gas.
In this problem, we have:
- The pressure of the gas is doubled: 
- The volume of the gas is doubled: 
Substituting into the equation, we find what happens to the temperature:
So, the correct choice is
a)The temperature of the gas in increased by four times its original value.
