In the above question find the acceleration of both the block when F = 36 N

Explanation

When `F = 36 N `
When `F gt 30` both the blocks will move separately so we treat each treat each block independently
F.B.D. of 2kg block

`a_(B) = 5 m//s^(2)`
F.B.D. of 4 kg block

`a_(A) = ( 36-10)/( 4) = (26)/( 4)m//s^(2)`
