Answer:
False
Explanation:
The charge on an electron as well as proton is same. The difference between electron and proton is that the electrons have a negative charge while the protons have positive charge.
The weight of an electron is, 
while the weight of a proton is 
.
Therefore, the given statement "A proton carries positive charge, and weights the same as an electron." is false.
Answer:
Magnitude of C= 
Angle=arctan(Ay+By/Ax+Bx)
Explanation:
Let
A = Axi + Ayj
B = Bxi + Byj
where i and j are unit vectors in the direction of x and y axes respectively.
C=A+B
C = (Ax + Bx)i + (Ay + By)j
The magnitude of vector C can be calculated by adding the square of magnitude of its componets and then taking sqaure root.
Magnitude of C=
And the angle will be
Angle=arctan(Ay+By/Ax+Bx)
If the total momentum of the insects is zero, this means all of the insects are at rest or are moving in opposite of each other. Same if the total kinetic energy is zero.
<h3>What is momentum? </h3>
Momentum is the quantity of motion which is multiplied by the amount of matter moved i.e., mass and the velocity at which it moves. Because, the object is in motion, it is a vector quantity, it has both direction and magnitude. It is determined by the product of the object's mass and the velocity of object.
If the total momentum of the insects is zero, this could mean anything of the two things. Either, all of the insects are at rest or an equal amount of insects are moving in opposite direction of each other which cancels out the total momentum of the insects.
If the total kinetic energy of the insects is zero, this means either all of the insects are at rest or an equal amount of insects are moving in opposite direction of one another which results into canceling out the energy.

Answer:
C) 7.35*10⁶ N/C radially outward
Explanation:
- If we apply the Gauss'law, to a spherical gaussian surface with radius r=7 cm, due to the symmetry, the electric field must be normal to the surface, and equal at all points along it.
- So, we can write the following equation:
- As the electric field must be zero inside the conducting spherical shell, this means that the charge enclosed by a spherical gaussian surface of a radius between 4 and 5 cm, must be zero too.
- So, the +8 μC charge of the solid conducting sphere of radius 2cm, must be compensated by an equal and opposite charge on the inner surface of the conducting shell of total charge -4 μC.
- So, on the outer surface of the shell there must be a charge that be the difference between them:
- Replacing in (1) A = 4*π*ε₀, and Qenc = +4 μC, we can find the value of E, as follows:
- As the charge that produces this electric field is positive, and the electric field has the same direction as the one taken by a positive test charge under the influence of this field, the direction of the field is radially outward, away from the positive charge.
The change in the gravitational potential energy is represented by the equation
u = ΔPE = Δmgh
since the mass of the system will remain constant and the acceleration due to gravity will also remain constant, the equation will become
u = mg Δh
