JEE Main 12 April 2023, Shift 1, Physics Q45

Question 45 of 90 in this shift, Physics question 15 of 30, Section A.

Three forces

F_1

=10 N,

F_2

=8 N,

F_3

=6 N are acting on a particle of mass 5 kg. The forces

F_2

and

F_3

are applied perpendicularly so that particle remains at rest. If the force

F_1

is removed, then the acceleration of the particle is:

(1)2 ms $^{-2}$ Official answer
(2)7 ms $^{-2}$
(3)4.8 ms $^{-2}$
(4)0.5 ms $^{-2}$
