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

Two blocks A and B of masses 2kg and 3kg are connected by a light string as shown in the figure and placed on a horizontal surface. `mu` between all surfaces is 0.1 and g = `10 ms^(-1)`. The acceleration of the system is, when the force applied F = 45N

Text Solution

Verified by Experts

`F -mu(m_(1) + m_(2)) g= (m_(1) + m_(2))`
`45-0.1 (50) 10 = 5a`
`45-5 = 5a`
`a = 8 ms^(-2)`
