Given that F = 3i - 12j, R = 7i + 5j and N = pi + qj are forces acting on a body, if the body is in equilibrium. find the values of p and q.
p=-10, q=7
p=-10, q=-7
p=10, q=- 7
p-10, q=7
Correct answer is C
If the body is in equilibrium then
F + R = N
3i - 12j + 7i + 5j = pi + qj
10i - 7j = pi + qj
p = 10, q = -7
