Statement: No work is done in taking a positive charge from one point to another inside a negatively charged metallic sphere.
Explanation:
When a positive charge is taken from one point to another inside a negatively charged metallic sphere, there is no change in the potential energy of the charge. This is because the electric field inside a conductor is zero.
Electric Field Inside a Conductor:
- Inside a conductor, the charges are free to move and redistribute themselves.
- In electrostatic equilibrium, the charges redistribute themselves in such a way that the electric field inside the conductor becomes zero.
- This is due to the fact that any electric field inside the conductor would cause the charges to move, and they will continue to move until the electric field becomes zero.
No Work Done:
- Work is defined as the product of force and displacement. If no force is acting or if the force and displacement are perpendicular to each other, no work is done.
- Inside a negatively charged metallic sphere, the electric field is zero. Therefore, no force is acting on a positive charge inside the sphere.
- As a result, the positive charge can be moved from one point to another inside the sphere without any force acting on it.
- Since no force is acting on the charge, no work is done in moving it from one point to another inside the sphere.
Conclusion:
The statement "No work is done in taking a positive charge from one point to another inside a negatively charged metallic sphere" is correct. This is because the electric field inside a conductor is zero, and hence no force acts on the charge inside the conductor.
