The nuclear charge (`Ze`) is non uniformlly distribute with in a nucleus of radius r. The charge densilty `rho(r)` (charge per unit volume) is dependent only on the radial distance r form the centre of the nucleus s shown in figure. The electric field is only along the radial direction.

The electric field within the nucleus is generaly observed to be linearly dependent on r. This implies

A

`a=0`

B

`a=R/2`

C

`a=R`

D

`a=(2R)/3`

Text Solution

Verified by Experts

The correct Answer is:
C
For `E prop r`, charge density should be constant so `a=R`
