Question

A negative charge particle enters an electric field in the direction of electric field.what is the nature of the path traced by it?​

Answer 1

Given:

A negative charged particle enters an electric filed in the direction of the field.

To find:

The nature of the path traced by the negatively charged particle.

Solution:

The force acting on the charged particle will be:

F = qE

Where q is the magnitude of the charge on the particle,

E is the magnitude of electric field.

Since F = ma = m dv/dt, so

m dv/dt = qE

on integrating both the sides:

v = qEt/m +c1

Integrating again:

x = qEt² / 2 + c1t + c2

This equation is an equation of a parabola.

Therefore the nature of the path of the charged particle is a parabola.

Answer 2

Answer:

parabola

Explanation:

particle moves along the straight line
