A point charge is located at O. There is a point P at a distance r from it. The electric field at point P is 500 V/m and a potential of 3000 V. Then the value of r is
Text Solution
Verified by ExpertsThe correct answer is:
A
Electric field due to a point charge
E = 
Electric potential due to a point charge
V = 
⇒ , 
= 
⇒ r = 
= 
= 6 metre
