Question : 35

Total: 50

The force per unit charge experienced at a point in a field is the

Solution:

Concept:

Force per unit positive charge defines electric field intensity.

Explanation:

Electric field intensity at a point is the electric force

F

experienced by a unit positive charge

q

placed at that point.

Mathematically,

E = \frac{F}{q}

Hence, force per unit charge is called electric field intensity.
