Answer:
Its initial position was 471 m.
Explanation:
We have,
Final position of the object is 327 m
Displacement of the object is -144 m
It is required to find its initial position. The difference of final and initial position is equal to the displacement of the object. So,
So, its initial position was 471 m.
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)
