Question:
If drift velocity of electron be \( v_d \) and intensity of electric field \( E \), then which relation among the following obeys Ohm's law?
If drift velocity of electron be \( v_d \) and intensity of electric field \( E \), then which relation among the following obeys Ohm's law?
Show Hint
Ohms law states that the drift velocity of charge carriers is proportional to the applied electric field, leading to a constant current for a given resistance.

- \( v_d \propto E^2 \)
- \( v_d = \text{Constant} \)
- \( v_d \propto E \)
- \( v_d \propto \sqrt{E} \)

The Correct Option is C
Solution and Explanation
The path of scattered \( \alpha \)-particles in Rutherford scattering is hyperbolic. When an \( \alpha \)-particle is scattered by a nucleus, the path is determined by the repulsive electrostatic force, resulting in a hyperbolic trajectory.
