Mark the correct statement:a)An electron and a proton when released fr...
Explanation:
The correct statement is option D: No work is done in taking a positive charge from one point to another inside a negatively charged metallic sphere.
Reasoning:
When a positively charged object is taken from one point to another inside a negatively charged metallic sphere, no work is done because the electric field inside a conductor is zero.
Explanation:
When a positively charged object is placed inside a negatively charged metallic sphere, the negative charges in the metallic sphere repel the positive charge, causing it to distribute evenly on the outer surface of the sphere. This redistribution of charges creates an electric field inside the sphere, which is opposite in direction to the external electric field.
Inside a conductor, the electric field is zero. This means that the force experienced by a positive charge inside the conductor is zero, and hence no work is done in moving the charge from one point to another inside the conductor.
This is because work is defined as the product of force and displacement, and when the force is zero, no work is done.
Key Points:
- Electric field inside a conductor is zero.
- The force experienced by a positive charge inside a conductor is zero.
- Work is the product of force and displacement.
- When the force is zero, no work is done.
