Which one of the following is not a a vector product of two vectors ?

A

Moment of a force (torque)

B

Force acting on a moving charge in a magnetic field

C

Work done in lifting a stone

D

Area of a triangle formed by two vectors `vec P and vec Q` as adjacent sides

Text Solution

Verified by Experts

The correct Answer is:
C
Work done in lifting a stone is a scalar product.
Torque, `tau = vec r xx vec F, F=q (vec v xx vec B)`
Area of the triangle `=(1)/(2)|vec P xx vec Q|` are examples of vectors product.
