JEE Main 25 July 2022, Shift 2, Physics Q35

Question 35 of 90 in this shift, Physics question 5 of 30, Section A.

For a free body diagram shown in the figure, the four forces are applied in the 'x' and 'y' directions. What additional force must be applied and at what angle with positive x-axis so that the net acceleration of body is zero ?

The figure, in words

A hatched circle (body) at the origin of x-y axes with four force arrows: 7 N pointing up along +y, 8 N pointing down along -y, 6 N pointing left (-x), 5 N pointing right along +x. Axes labelled y and x.
