JEE PHYSICS MCQ: ELECTRIC FIELDS AND CHARGES

1 Medium

1 of 1

Application +4 | -1

An electron of mass

{M_e},\;

initially at rest, moves through a certain distance in a uniform electric field in time

{t_1}.\;

A proton of mass

{M_p}

also initially at rest, takes time

{t_2}

to move through an equal distance in this uniform electric field, neglecting the effect of gravity, the ratio

{t_1}/{t_{2\;}}

is nearly equal to

View answer and explanation

Correct option: B

\sqrt {{M_p}/{M_e}}

Option B (

\sqrt {{M_p}/{M_e}}

) is correct because it is derived from the relationship between time, distance, mass, and acceleration in a uniform electric field.

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
