PhysicsMediummultiple choice

Two point charges $Q_{1}$ and $Q_{2}$ lie along a line at a distance from each other. Figure show the potential variation along the line joining the charges

Options:(select one or more)

Answer:

A, C, D

Solution:

The potential near $Q_{1} \to \infty$ and near $Q_{2} \to - \infty$

$∴ Q_{1} is positive, Q_{2} is negative V_{2} = 0 ∴ Q_{1} has greater magnitude than Q_{2} \frac{d v}{d r} = 0 at 3. ∴ E = 0 at 3$
