STANDARD Physics Angular Velocity and Linear Velocity MCQ Question
A body is rotating with angular velocity ω = (3î - 4ĵ + k̂). The linear velocity of a point having position vector r = (5î - 6ĵ + 6k̂) is
6î + 2ĵ - 3k̂
18î + 3ĵ - 2k̂
-18î - 13ĵ + 2k̂
6î - 2ĵ + 8k̂
Correct Answer
Detailed Explanation
The linear velocity v is given by the cross product v = ω × r. Calculating the cross product gives v = -18î - 13ĵ + 2k̂, which matches option B.
