The electric field due to a point charge at a distance r depends accor

1.	The electric field due to a point charge at a distance r depends according to inverse square law . State how the following quantities depend upon r.(i) potential due to a point charge(ii) potential at a distance r from the centre of a charged metallic sphere of radius R (r < R).
Answer» The relation between potential and R can be given by the following formulas The potential DUE to a POINT charge is given by the formula V = q / 4πε₀r In this case the potential is inversely proprtional to r i.e, V∝ r⁻¹ Potential at a distance r from the center of sphere of RADIUS R is given by the formula V = q / 4πε₀R In this case the potential does not depends on r i.e, V∝ r⁰

The electric field due to a point charge at a distance r depends according to inverse square law . State how the following quantities depend upon r.(i) potential due to a point charge(ii) potential at a distance r from the centre of a charged metallic sphere of radius R (r < R).

Answer»

The relation between potential and R can be given by the following formulas

The potential DUE to a POINT charge is given by the formula

V = q / 4πε₀r

In this case the potential is inversely proprtional to r i.e, V∝ r⁻¹

Potential at a distance r from the center of sphere of RADIUS R is given by the formula

V = q / 4πε₀R

In this case the potential does not depends on r i.e, V∝ r⁰
