NEET Physics Equilibrium of Forces MCQ Question
A particle is in equilibrium under the action of three concurrent forces F1, F2, and F3, with magnitudes 30 N, 40 N, and F3 respectively. If the angle between F1 and F2 is 90 degrees, what is the magnitude of F3?
50 N
70 N
10 N
60 N
Correct Answer
Detailed Explanation
For equilibrium, the vector sum of the forces must be zero. Using the Pythagorean theorem for F1 and F2, F3 = sqrt(F1^2 + F2^2) = 50 N.
