Dual Nature Of Light Question 31

Question: In the Millikan’s experiment, the distance between two horizontal plates is 2.5 cm and the potential difference applied is 250 V. The electric field between the plates will be

Options:

A) 900 V/m

B) 10000 V/m

C) 625 V/m

D) 6250 V/m

Show Answer

Answer:

Correct Answer: B

Solution:

Electric field $ =\frac{V}{d}=\frac{250}{2.5\times {{10}^{-2}}}=10000\ V/m $ .
