Question

Two protons $P_1$and $P_2$ and electron e lie on a straight line as shown in figure. The direction of the net electric force on $P_1$,$P_2$ and $e$are shown. Mark the correct option.

• A.

  

• B.

  

• C.

  

• D.

  

• E.

  

Answer 1

The correct option is D

1. Here, the nature of the charge on the proton is positive, and the nature of a charge on the electron is negative, so the nature of force between electron and proton will be attractive.
2. Here, the direction of the forces on the electron due to protons is given below.
3. Here, the operation between p1, and e is less than the separation between p2 and e so the magnitude of the force between p1 and e will be more so the direction of the net force will be toward the left (toward p1).
4. Thus, the direction of the forces is given below.

Hence Option D is the correct answer

Therefore, option D is the correct answer.
