Question

Which of the following quantities is a scalar?

• A. magnetic moment
• B. acceleration due to gravity
• C. electric field
• D. electrostatic potential

Answer 1

The correct option is D electrostatic potential

Magnetic moment, acceleration due to gravity and electric field are vector quantities while electrostatic potential is a scalar quantity.
Electrostatic potential is the work done in moving a unit positive charge from infinity to that point.

1. The magnetic moment of a magnet is a quantity that determines the torque it will experience in an external magnetic field
2. Acceleration due to gravity is the force experienced by an object in the Earth's gravitational field.
3. Electric field is the force experienced by a charge placed in a field.
