" the fixed point charges the and te wite "

Two point charges Q are kept fixed on XY-plane at points A(0, d) and B(0, -d). Another point charge -q with mass m is held at a point, on the positive side of X-axis that is at the distance 2d from both the fixed point charges. What will be the magnitude of acceleration of the negative point charge (i) just after it is released from its location? (ii) at an instant it crosses the origin?

Two fixed point charges +4e and +e units are separated by a distance a. Where should a third point charge be placed for it to be in equilibrium?

Two fixed point charges +4e and +e units are separated by a distance a. Where should a third point charge be placed for it to be in equilibrium?

Two fixed point charges +9e and +4e units are placed on a straight line AB= a at A and B respectively . Where should the third point charge be placed on AB for it to be in equilibrium ?

A point charge Q is moved along a ciruclar path around another fixed point charge. The work done is zero

Two fixed point charges +9e and +4e are separated by a distance x.Where should a point charge be placed between the two charges, so that it is in equilibrium?

Two fixed point charges +4q and +q units are separeted by a distance 'x'. Where should a third point charge- q_0 be placed for it to be in equilibrium?

Consider the points lying on a straight line joining two fixed opposite charges. Between the charges there is
