A free proton and a free electron are placed in a uniform electric field. Which of the following statements are correct?
A. The magnitudes of electric forces acting on them will be equal.
B. Their accelerations will be different.
C. They will move in the same direction.
Select the correct answer using the code given below.
A. The magnitudes of electric forces acting on them will be equal.
B. Their accelerations will be different.
C. They will move in the same direction.
Select the correct answer using the code given below.
View answer and explanation
Correct option: A
A and B only
Option A (A and B only) is correct because the magnitudes of the electric forces are equal, and their accelerations are different due to mass difference.

Assertion:- Electric field lines do not cut at any point.
Reason:- At any point, there is only one direction of electric field. Statement-I: A positive point charge is brought in an electric field, the electric field at neary by point will increase
Statement-II: Electric field produced by charge may favour the existing electric filed Two particles having equal mass and charge
are separated by a distance The force(s) they
experience is (are) Statement-I: No 2 electric lines of force can intersect each other
Statement-II: tangent at any point of electric line of force gives the direction of electric field A force of is acting between two charges in air if the space between them is completely filled with glass , then the new force will be …… An electron is placed at centre of a conducting sphere of radius 0.2 metre having charge coulomb. The force of on the electron is ________ N
