NEET Physics Torque MCQ Question

Type: MCQ-numerical-Medium-Class 11

The force 7î + 3ĵ − 5k̂ acts on a particle whose position vector is î − ĵ + k̂. What is the torque of a given force about the origin?

A

2î + 12ĵ + 10k̂

B

2î + 10ĵ + 12k̂

C

2î + 10ĵ + 10k̂

D

10î + 2ĵ + k̂

Correct Answer

Option A

Detailed Explanation

Torque is given by τ = r × F. Calculating the cross product of the position vector and the force vector gives the torque.
