Two blocks A and B of masses 2 kg and 3k...

Two blocks A and B of masses 2 kg and 3kg are connected by a light string as shown in the figure and place on a horizontal surface. `mu` between all surface is 0.1 and g = 10 `ms^(-2)`. The acceleration of the system is, when the force applied F = 45 N.

Text Solution

Verified by Experts

`F-mu (m_(1)+m_(2))g=(m_(1)+m_(2))`
`45-0.1(5)10=5a`
`45-5=5a`
`a=8 ms^(-2)`
