Question

Four charges are rigidly fixed along the Y-axis as shown.
A positive charge approaches the system along the X axis
with initial speed just enough to cross the origin. Then its
total energy at the origin is?​

Answer 1

Answer:

0

Explanation:

if it has just the enough energy to cross origin, the energy is kinetic. Hence at the origin speed is some positive vale and the potential energy is negative of KE
