If a proton is moved against the coulomb force of an electric field, then
- A work is done by the electric field
- B energy is used from some outside source
- C the strength of the field is decreased
- D the strength of the field is increased
Answer & Solution
Correct Answer
(B) energy is used from some outside source
Step-by-step Solution
Detailed explanation
Due to field, a proton experiences a force in the direction of field. To move proton against the field an external agency is required to provide energy to the proton.
