A small magnet M is allowed to fall through a fixed horizontal conducting ring R. Let g be the acceleration due to gravity. The acceleration of M, a will be
Text Solution
Verified by ExpertsThe correct answer is:
A
In the case , the induced current in the ring will be in such a direction that it repels the magnet.
i.e. 
and moving towards R.
In case , the induced current is such as to attract the magnet.
i.e. 
not 
and moving away from R. So, option is incorrect.
