Question

A block is kept on a frictionless inclined plane with angle of inclination x. The plane is given an

acceleration a to keep the block at rest. Then a is equal to

(a) g

(b) g tan x

(c) g/ tan x

(d) g/sin x
​

Answer 1

Answer:

option c is the correct answer plz give me brilliant

Answer 2

Answer:

g tan x

Explanation:

In the reference frame of the wedge, pseudo force ma acts towards right and component of this ma is ma cos x  balances the  mg sin x.

mg sin x=ma cos x

⇒x=g tanx
