  4. Two smooth blocks are placed at a smooth corner as shown in figure. Both the blocks are having mass m. We apply a force F on the small block m. Block A presses block B in the normal direction, due to which pressing force on vertical wall will increase, and pressing force on the horizontal wall decreases, as we increases F(θ=37°. with horizontal). <img class=img-fluid question-image alt=image src=https://cdn.tardigrade.in/img/question/physics/fd417b1e0bb30121932d4d3c8d0847ae-.png /> As soon as the pressing force on the horizontal wall by block B becomes zero, it will lose contact with ground. If the value of F further increases, block B will accelerate in the upward direction and simultaneously block A will move towards right. If both the blocks are stationary, the force exerted by ground on block A is

Q. Two smooth blocks are placed at a smooth corner as shown in figure. Both the blocks are having mass . We apply a force on the small block . Block presses block in the normal direction, due to which pressing force on vertical wall will increase, and pressing force on the horizontal wall decreases, as we increases with horizontal).

As soon as the pressing force on the horizontal wall by block becomes zero, it will lose contact with ground. If the value of further increases, block will accelerate in the upward direction and simultaneously block will move towards right.
If both the blocks are stationary, the force exerted by ground on block is
