A very large, charged plate floats in deep space. Due to the charge on the plate, a constant electric field E exists everry above the plate. An object with mass m and charge q is shot upward from the plate with a velocity v and at an angle `theta`. It follows the path shown reaching a height h and a ramge R. Assume the effects of gravity to be negligible.

Which of the following must be true concentration the object?

A

q must be positive

B

q must be negative

C

m must be large

D

m must be small

Text Solution

Verified by Experts

The correct Answer is:
B
`:'` Gravity is absent and path of the particle is parabola i.e. a downward (qE) force is necessary.
