A proton and an electron are released from
an infinite distance apart and they get
attracted towards each other. Which of the
following statement about their kinetic
energy is true?
an infinite distance apart and they get
attracted towards each other. Which of the
following statement about their kinetic
energy is true?
View answer and explanation
Correct option: A
Kinetic energy of electron is more than
that proton
that proton
Option A (Kinetic energy of electron is more than that proton) is correct because, due to conservation of momentum, the lighter electron will have a higher kinetic energy than the heavier proton.

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
