Question

a charged particle is moving in a uniform electric field which quantity does not change ​

Answer 1

Answer:acceleration

Explanation:As, F=q. E

And F=ma

So, a=q. E/m

Here, q, E(uniform electric field) and m are constant

S

Therefore, acceleration (a) is also constant. Velocity changes due to acceleration.

Answer 2

Given:

Let

charge on a particle=q

Uniform electric field=E

To find:

The quantity which does not change during motion of charged particle in uniform electric field

Solution:

We know that

Force on charged  particle=$charge\times electric\;field$

Force on charged  particle,F=q E

Force,F= ma

a=F/m

Substitute the values

a=qE/m

Where

q=Constant

E=Constant

m=Mass of particle is constant

Therefore, a= Constant

Hence, acceleration of the particle is constant during motion in a uniform electric field.

Quantity: Acceleration does not change
