Two blocks on a rough incline are connected by a light string that passes over a frictionless light pulley as shown. Assuming `m_(1) gt m_(2)` and takingthe coefficient of kinetic friction for each block to be `mu` we get acceleration of the blocks as -

Options

A. `a = ([(m_(1) -m_(2)) sin theta - mu ( m_(1) + m_(2)) cos theta ] g)/((m_(1) + m_(2)))`for `m_(1)`
B. `a = (mu[(m_(1) +m_(2)) cos theta - ( m_(1) - m_(2)) sin theta ] g)/((m_(1) + m_(2)))`for `m_(2)`
C. `a = g ( sin theta - mu cos theta ) `
D. `a =g ( cos theta - mu sin theta ) `

Answer

A, B
