JEE Main Physics question
A block of mass m is placed on a smooth wedge of inclination θ. The whole system is accelerated horizontally so that the block does not slip on the wedge. The force exerted by the wedge on the block (g is the acceleration due to gravity) will be
Answer: (D)
Solution
For the block not to slip on the smooth (frictionless) wedge, the whole system must accelerate horizontally at a = g tanθ, so that the only contact force (the normal
