Question

**IP** A charge of 22.0 μC is held fixed
at the origin.

Part A

If a -5.50 μC charge with a mass of 3.70 g is released from rest at the position (0.925 m, 1.17 m), what is its speed when it is halfway to the origin?

PART B

Suppose the -5.50 μC charge is released from rest at the point x =
1/2(0.925m) and y = 1/2(1.17m). When it is halfway to the origin,
is its speed greater than, less than, or equal to the speed found
in part A?

PART C

Find the speed of the charge for the situation described in part B.
