Answer 1

CONCEPT:

Scalar quantities	Vector quantities
The physical quantities which have only magnitude and no direction are called scalar quantities or scalars.	The physical quantities which have both magnitude and direction and obey the laws of vector addition are called vector quantities or vectors.
A scalar quantity can be specified by a single number, along with the proper unit.	A vector quantity is specified by a number with a unit and its direction.
Examples: Mass, volume, density, time, temperature, electric current, distance, Energy, speed, etc.	Examples Displacement, velocity, force, weight, torque, momentum, acceleration, velocity, etc

EXPLANATION:

The dipole moment is the product of charge and the distance between them.
- It is a vector quantity. Therefore option 4 is correct.
The rate of flow of charge is called electric current.
- It is a scalar quantity.
Power (P): It is defined as the rate at which work is done.
- It is a scalar quantity.
The gravitational potential energy of a body is the energy associated with it due to its position in the gravitational field of another body and is measured by the amount of work done in bringing a body from infinity to a given point in the gravitational field of the other.
- It is a scalar quantity because work is not a vector quantity.
