Initialy spring is in the natural length and blocks `A & B` are at rest. Find maximum value of constant force `F` that can be applied on `B` such that block `A` remains at rest. `(g = 10 m//s^(2))` (given answer in Newton) |

Answer» Correct Answer - 3 Initially spring …………….. Values of `mu mg` for A and B are `2N & 2N` Worck energy theorm on `B` gives `Fx-2x-(K//2)x^(2)=0` `F=2+kx//2` ……(i) For equilibrium of `A kx = mu mg = 2` so `F = 2+1=3N` |
