Figure shown two blocks A and B connected to an ideal pulley string system. In this system when bodies are released then:(neglect friction and take`g=10(m)/(s^2)`)

A

Acceleration of block A is `1(m)/(s^2)`

B

Acceleration of block A is `2(m)/(s^2)`.

C

Tension in string connected to block B is 40 N

D

tension in string connected to block B is 80 N

Text Solution

Verified by Experts

The correct Answer is:
B, D

Applying NLM on 40 kg block
`400-4T=40a`
For 10 Kg block `T=10.4a`
Solving `a=2(m)/(s^2)`
`T=80N`
