Select the correct answer out of the options given against each question and write in the box provided on rigth hand side bottom:
+ q point charge is placed at the centre of a hemispherical surface . Amount of electrical flux crossing through the surface will be

A

`(q)/(epsilon_(0))`

B

`(q)/(2epsilon_(0))`

C

`(q)/(3epsilon_(0))`

D

`(2q)/(epsilon_(0))`

Text Solution

Verified by Experts

Considering all directions, the total flux around the point charge = `(q)/(epsilon_(0))`
The hemispherical surface surrounds half the entire space. So the flux through the surface = `(1)/(2) (q)/(epsilon)`
