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)]`.
