The magnitude of acceleration of centre of mass of the system is

A

4m/s

B

`10m/s^2`

C

`5m/s2`

D

`2sqrt2m/s^2`

Text Solution

Verified by Experts

The correct Answer is:
(D)
`a=("Net force on system")/("total mass of system")=(5g-mu(5g))/(5+5)=(50(1-0.2))/10=4m/s^2 a_cm=|(m_1veca_1+m_2veca_2)/(m_1+m_2)|=a/sqrt2=2sqrt2m//s`
