To solve this problem we will apply the mathematical consideration of the electric field on an axial axis of a ring. This definition is already established mathematically and is a subordinate of the definition of the magnetic field of Coulomb's laws. It can be expressed as,
Here,
k = Coulomb's constant
Q = Charge
x = Distance on the axial line
R = Radius of the circle or ring
At x = 1 cm, we have that the total charge is 66.0 μC and the radius 0.1m, then replacing,
Therefore the electric field on the axis of the ring is 5.85MN/C
Answer:
(a). The time is 26.67 sec.
(b). The distance traveled during this period is 1066.9 m.
Explanation:
Given that,
Speed = 80 m/s
Acceleration = 3 m/s
Initial velocity = 0
(a). We need to calculate the time
Using equation of motion
Put the value into the formula
The time is 26.67 sec.
(b). We need to calculate the distance traveled during this period
Using equation of motion
The distance traveled during this period is 1066.9 m.
Hence, This is the required solution.
A box residing on an inclined plane has following forces:
In the X- direction
Mg sin (theta) = horizontal component of weight of the box
f = Frictional force = uN , u = frictional factor, N= mg
In the Y- direction
upward force = Normal reaction of the box = mg
downward force = mg cos(theta) = vertical component of weight of the box
