Question details

Hello I am finding issues with a problem I am trying to solve. The questions asks:

Two identical point charges (q=+1.70 x 10-^6 C) are fixed at opposite corners of a square whose sides have a length of L=0.620 m. A test charge (qo=-1.90 x 10^-8 C), with a mass of m=7.00 x 10^-8, is released, starting from rest, at one of the corners of the square. All three charges are on a horizontal, frictionless surface.

A) What is the magnitude of the resultant electrostatic force on the test charge, qo, due to the other 2 charges, when qo is located at the corner of the square?

B) What will be its speed, vf, of the test charge, qo, when it reaches the center of the square?
