A body having an excess of 10 ^6 electrons is placed in an electric field of 1000 n /c towards east. find out the magnitude and direction of the force acting on the body.

Answer»

Answer:

Electric force, F = 1.6 × 10⁻¹⁰ N and its direction is inwards

Explanation:

It is given that,

NUMBER of electrons, e = 10⁶

TOTAL charge, <klux>Q</klux>=1.6\times 10^{-19}\times 10^6\ C=1.6\times 10^{-13}\ C

Electric field, E = 1000 N/C

Electric force is given by the product of electric charge and electric field.

i.e. F = q E

F=1.6\times 10^{-13}\ C\times 1000\ N/C

F=1.6\times 10^{-10}\ N

As the electrons are negatively charged particles. The direction of electric filed for electrons is NEGATIVE.
