As shown in the figure, if acceleration of M with respect to ground is 2 ms-2, then 

a
Acceleration of m with respect to M is 5 ms-2.
b
Acceleration of m with respect to ground is 5 m s-2
c
Acceleration of m with respect M is 2 ms-2
d
Acceleration of m with respect to ground is 10 m s-2

detailed solution

Correct option is C

If acceleration of M is 2 m s-2, then acceleration of m w.r.t. M will be 2 ms-2a→m=a→m/M+a→MAcceleration of m w.r.t. groundam=22+22+2×2×2cos⁡180−37∘=8/5ms−2
