Initially both blocks are at rest on a horizontal surface and string is just tight. At t=0, two constant horizontal force `F_(1)` and `F_(2)` start acting on blocks as shown. `f_(1)` and `f_(2)` are frication foces acting on `10 kg` and `20 kg` block (co-efficient of frication between and ground are `0.5`). Values of `F_(1)` and `F_(2)` are given column-I. Then match magnitudes of `f_(1), f_(2)` and direction of `overset(vec)(f_(1))` with corresponding values of `F_(1)` and `F_(2)` given in column-I
`[g = 10 m//s^(2)]`.

Options

A. for `P lt F_(0), T=0`
B. for `F_(0)lt P lt 2F_(0), T=P-F_(0)`
C. for `Pgt 2F_(0), T=P//2`
D. none of the above

Answer

A, B, C
