Two spheres of masses 3 kg and 4 kg are ...

Two spheres of masses 3 kg and 4 kg are attached to ends of a string which passes over a frictionless pulley. Take `g = 9.8 m//^2`. The relative acceleration of the system is

A

`4 ms^(-2)`

B

`1.4 ms^(-2)`

C

`3 ms^(-2)`

D

`2.8 ms^(-2)`

Text Solution

Verified by Experts

The correct Answer is:
B
Acceleration `= ((m_2-m_1))/(m_2+m_1) g = ((4-3))/((4+3))xx9.8 = 98/7=14 ms^(-2)`
