In the figure, a proton moves a distance `d` in a unform electric `vecE` as shown in the figure. Does the electric field do a positive or negative work on the proton? Does the electric potential energy of the proton increase or decrease?

A proton moves a distance d in a uniform electric field E ®as shown in the figure. Then which of the following statements are correct ? (1) Electric field do a negative work on the proton (2) Electric potential energy of the proton increases (3) Electric field do a positive work on the proton (4) Electric potential energy of the proton decreases

If a proton is brought towards another proton, the electrical potential energy of the system

An electron and proton are placed inside a uniform electric field.

A proton and an electron are placed in a uniform electric field.

A proton and an electron are placed in a uniform electric field.

A proton and an electron are placed in a uniform electric field.

A proton and an electron are placed in a uniform electric field . Then

IF the strength of the electric current increases, does the magnetic field increase or decrease?

The field lines corresponding to an electric filed is shown in the figure then ( E denotes electric field and V denotes electric potential)
