Question

9.
Three equal masses of 3 kg each are placed at the
vertices of an equilateral triangle PQR and a mass
of 4 kg is placed at the centroid O of the triangle
which is at a distance of 12 m from each of the
vertices of the triangle. The force, in newton, acting
on the mass of 4 kg is :-
(1) 2
(2) 2
(3) 1
(4) zero​

Answer 1

Answer:

option 2

Explanation:

please follow me please please please

Answer 2

Answer:
