Question

Two forces equal to 2F and F act on a particle. If the first be doubled and the second increased
by 15 N, the direction of the resultant force remains unaltered. Find the value of F.

Answer 1

Answer:

because resultant force remains equal ,so means that both are in opposite direction . so , according to the question , resultant force is unchanged . hence , F = 20 N .
