Answer:
Explanation:
Given
Car drives 215 km east and then 45 km North
Displacement is East direction is
Now, the displacement from that to 45 km North is given by
Net displacement is
Magnitude of the displacement is
the potential at the center of curvature of the arc = v = Q ∕ (4πε∘a) or
ATQ,
We have density of charge,
λ =
Where L is the rod's length, in this case the semicircle's length L = πr
Q is the charge on the rod
The potential created at the center by an differential element of charge is:
where k is the coulomb's constant
r is the distance from dQ to center of the circle
v = ∫ , Where a = radius, k = 1 / 4πε∘
v = or Q ∕ (4πε∘a)
