The electric field due to an extended charge distribution spread over all space is given by E = q 4 ₀ r^2 (1+ r ) e^ - r r Here and q are positive constants and the electrostatic potential is taken to be zero at infinity. Select the correct statement(s).
Options
- AThe electrostatic potential is q e^ - r / 4 ₀ r .
- BThe total charge is zero.
- CThe flux through a Gaussian sphere centred at the origin and of radius R decreases as we decrease R .
- DThere is a positive charge at the origin.
