Question

The electric flux Φ through a hemisphere surface of radius R, placed in a uniform electric field of intensity E parallel to the axis of its circular plane is

• A. 2πRE
• B. 2πR²E
• C. πR²E
• D. $\left( \frac{4}{3} \right)\pi R^{3}E$

Answer 1

Answer: (C)

πR²E

Answer 2

Electric flux through any surface is equal to the product of electric field intensity at the surface and component of the surface perpendicular to electric field

= E x πR² = πR²E
