The axle of a wheel lies on the surface of an oil bath, and four equal charges q are spaced equally around the perimeter. The fixed charge Q repels all four charges q. What do you predict will happen to the wheel?
3i expect that the system will rotate,bcos the charge in the lower position experiences lesser force than the upper one,and also the charge nearer to the Q charge experience more repulsion,and all the charges were constraint to move,So it will be in circular motion.
11Is the lower charge inside the oil bath? If so then force acting on it will be different then the upper charge due to permitivity being different. Then the wheel will rotate
24I never opposed u..i told that u should wrote torque in place of force [1]
1The ball rotates clockwise ...and starts shifting towards right...I guess
