Question

Two conducting parallel plates are separated by a distance of 0.001 m. A 9 V battery is connected across the plates. Find out the electric field between the plates ?

• A. 9000 V/m.
• B. 900 Vim.
• C. 9 V/m
• D. 0.009 V/m
• E. 0.00011 V/m

Answer 1

Answer: (A)

9000 V/m.

Distance between the plates $d=0.001$ m

Voltage of the battery $V=9$ volts

Thus electric field between the plates $E=\frac{V}{d}=\frac{9}{0.001}=9000$ V/m
