Question

a charge of 5c is kept at the centre of radius 1m . what is the flux passing through the sphere?​

Answer 1

Answer:

The final answer is $5.65 * 10^{11} Vm$

Explanation:

Given,

q = 5c

r = 1m.

We need to find the flux passing through the sphere. We know that magnetic flux is simply the electric field in a confined area. When the electric field moves in an area, current is generated in the area and magnetic flux will be generated. This magnetic flux is the product of electric field E and area of the space A. This is given by the formula,

Flux = E * A

Flux = E * 4 * $\pi$ * r

E = $q0 * q / r^2$

q0 = $9 * 10^9$

E = $9 * 10^9 * 5 /1^2$

Flux = $9 * 10^9 * 5 * 4 *\pi*5*5$

Flux = $5.65 * 10^{11} Vm$
