In the given arrangement all surfaces are smooth. What acceleration should be given to the system, for which the
block m2 doesn't slide down?
@Aditya
m1 and m2 doesn't slide down. means, m1 and m2 are rest with respect to M.
now draw free body daigram for m1 and m2
in case of m1,
T = m1a ........(1)
in case of m2,
T = m2g........(2)
from eqs. (1) and (2),
