NEET Physics Equilibrium of Forces MCQ Question

Type: MCQ-numerical-Hard-Class 11

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?

A

50 N

B

70 N

C

10 N

D

60 N

Correct Answer

Option A

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.
