Answer question on the basis of your understanding of the following paragraph and the related studied concepts.
A Charges placed at a point in space produces an electric field everywhere in the surrounding. When another charge is borught in the field of first charge, it experiences a force . The electric field at a point is space due to given charges is defind as the force that a unit positive charges would experience if placed at that point.
It we consider a system of charges `q_1, q-2,q_3 .....` with position vectors `oversetto (r_1 ) , oversetto (r_2) , oversetto (r_3) .....` relative to some origin O, then electric field at a point in space due to the system of charges is determined by finding the vector sum of fields due to all individual charges of the charges system.
State the SI unit of electric field.

Explanation

SI units of electric field is `NC^(-1) ` and it is also expressed as `Vm^(-1) `
