1 of 1

Application +4 | -1

If a charged particle

(+q, m)

is projected along

+x

direction with initial velocity

u

and an uniform electric field exist in space along (

-

ve)

y

-direction then path of partcile is (neglect gravity)

View answer and explanation

Correct option: C

Parabolic

Option C (Parabolic) is correct because the particle experiences constant force in the y-direction and has initial velocity in the x-direction, resulting in parabolic motion.

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
