Electrostatics Question 484
Question: Two plates are at potentials ?10 V and +30 V. If the separation between the plates be 2 cm. The electric field between them is [Pb. PET 2000]
Options:
A) 2000 V/m
B) 1000 V/m
C) 500 V/m
D) 3000 V/m
Show Answer
Answer:
Correct Answer: A
Solution:
$ E=\frac{V}{d}=\frac{30-(-10)}{(2\times {{10}^{-2}})}=2000V/m. $
