Answer:
A) normal reaction is mgcos∅ = 10*9.8*cos(37°) = 98*4/5 = 78.4N
B) tension in the thread is mgsin∅ = 10*9.8*sin(37°) = 58.8N
c) when moving with acceleration , the pseudo force will be ma so, for lifting of block the normal reaction should be 0.
now, Masin(37°) = Mgcos(37°)
==> a*3/5 = 10*4/5
=> a = 40/3 = 13.33 m/s²
