Consider the quantities , pressure, power, energy impulse, gravitational potential, electrical charge , temperature, area,Out of these, the only vector quantities are .

Options

A. impulse, pressure and area
B. impulse and area
C. area and gravitational potential
D. impulse and pressure

Answer

B

Explanation

We know that impulse `J=F. Deltat=Deltap`, where F is force, `Deltat` is time duration and `Delta p` is change in momentum. AS `Deltap` is a vector quantity , hence impulse is also a vector quantity. Sometimes area can also be treated as vector.
