Question

A block of mass m is places on a smooth wedge of inclination

Answer 1

Answer:

Heya!!

Explanation:

A block of mass m is placed on a smooth wedge of inclination theta.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 has a magnitude.

Answer 2

Explanation:

                                         Here we should take Pseudo force ( it will be toward the opp side of acceleration)

At eqm

macosθ = mgsinθ

           a = g tanθ

Condition for the block to not slip

Normal should be balanced with he net downward forces

N = mg cosθ + m a sinθ

  =mg cosθ + m g tanθ sinθ

 = mgcosθ + mgsin²θ /cosθ

 =  mg cos²θ + mgsin²θ

                 cosθ

                            N  = mg/ cosθ

                Hope you understand
