Question

2. In the situation given, all surfaces are frictionless, pulley is ideal and string is light, F
acceleration of block 2
, find the​

Answer 1

Answer:

The acceleration of block 2 is g/2 means according to the image the correct answer will be option 2

Explanation:

From the diagram let the acceleration of the block 2 is s

From the diagram we can see that the block 2 is shifting in the forward direction by the action of force f = mg/2 .[ where m is the mass of block 2 and g is gravitational force]

Therefore,  

ms =mg/2

or s=g/2

Answer 2

Answer:g/4

Explanation:

As f=mg/2 for the whole system so total mass=2m so f=ma

mg/2=2ma

a=g/4
