# A lift of mass m is moving upwards direction with acceleration g/4 , its dispalcement is 'n' . Find out work done by tension force  Your Option is correct !!A.1/4 mgh B.5/4 mgh C.2 mgh D.3/4 mgh

S safeer

T - mg = m (g/4)

T = 5/4 mg

$W = FS \cos \theta$

$W = [ 5/4 mg ] h \cos \theta$

W = 5/4 mgh
