In the adjacent figure `BE bot` DA and CD`bot`DA then prove that m`angle1 ~= m angle3`.

Answer

A, B, C, D

Explanation

a. `=F/(2(M+m))` (given)

From `ma=muR_1`
and `R_1=mg`
`rarr =mu=(ma)/R_1`
`=F/(2(M+m)g)`
b. FrictioN/Al froce acting on the smaller block
`f=muR= F/(2(M+m)g)xxmg`
`=(mF)/(2(M+m))`
c. work done `w=fs `
`s=d`
`=(mF)/(2(M+m))xxd`
`=(mFd)/(2(M+m))`
