Question

Two mass m and 2m are attached with each other by a rope
passing over a frictionless and massless pulley. If the pulley
is accelerated upwards with an acceleration ‘a’, what is the
value of T?
(a)g + a/3
(b)g - a/3
(c)4m(g + a)/3
(d)m(g - a)/3

Answer 1

Answer:

The force balance equation for 2m will be

2mg−T=2ma2mg−T=2ma

And for m, it will be

T−mg=maT−mg=ma

Solving for a, we get

{eq}a=\dfrac{...
