PHXII05:MAGNETISM and MATTER

360409 Assertion :
Two short magnets are placed on a cork which floats on water. The magnets are placed such that the axis of one produced bisects the axis of other at right angles. Then, the cork has neither translational nor rotational motion.
Reason :
Net force on the cork is zero
