Direction for: In each of the following questions a statement of Assertion is given followed by a corresponding statement of Reason just below it. Of the statements mark the correct answer as
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.
A) If both Assertion and Reason are true and the Reason is the correct explanation of the Assertion
B) If both Assertion and Reason are true but the Reason is not the correct explanation of the Assertion
C) If Assertion is true but Reason is false
D) If both Assertion and Reason are false
Correct Answer: A
Solution :
We observe that both the magnets exert equal and opposite force/torque on each other. Hence, net force/torque on cork will be zero.
