Question

A cylinder of radius R and length L is placed in a uniform electric field E parallel to the cylinder axis. The total flux for the curved surface of the cylinder is given by-

• A. 2pR²E
• B. pR²LE²
• C. $\frac{\pi R^{2} + \pi R^{2}}{EL}$
• D. Zero

Answer 1

Answer: (A)

2pR²E

Answer 2

f = E . A

= (10 + 3 + 4) . (10 ) = 100 units
