A charge of 19.0 μC is held fixed at the origin.
1. If a -5.00 μC charge with a mass of 3.10 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? v
=  m/s
2. Suppose the -5.00 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?

a. Greater than the speed found in part A

b. Lee than the speed found part in A

c. Equal to the speed found in part A

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

v =

m/s
