JEE Main 25 June 2022, Shift 2, Physics Q53

Question 53 of 90 in this shift, Physics question 23 of 30, Section B.

A block of mass 200 g is kept stationary on a smooth inclined plane by applying a minimum horizontal force F=x NF = \sqrt{x}\,N as shown in figure. The value of xx = ____________.

The figure, in words

An inclined line rising to the right makes an angle labelled 60° with a horizontal line at its foot. A hatched block labelled 200 g sits on the inclined line; a horizontal arrow labelled F points right toward the block from the left.

Official answer

12
