One or more than one correct:
a negative point chage placed at the point A is:
A in stable eqm along x-axis
B in unstable eqm along y axis
C in stable eqm along y-axis
D in unstable eqm along x-axis
plaese xplain in detail

D in unstable eqm along x-axis.

it is not important where u stand, but in which direction u are moving |

ANSWER WILL BE UNSTABLE EQUILIBRIUM ALONG X-AXIS AND STABLE EQUILIBRIUM ALONG Y AXIS

tomorrow.
i think i solved it. if it is +ve charge it will execute shm alog y axis.
i shall check tomorrow.

see acc. to definitions of the stable and unstable equilibriums, in this case if we move the middle charge along x-axis then the force of attr btw the middle charge and the charge towards which its moved will increase...........hence unstable equilibrium

similarly if we move the charge along y axis then the horizontal componenta are cancelled and the vert comps add up. therefore the forces tend to bring the charges back to the initial position and hence stable equilibrium..........
