Question

1. Assume that earth has a surface charge density of 1 electron per

metre2

. Calculate the earth’s electric field.

​

Answer 1

Answer:

The surface charge density is present only in conducting surfaces and describes the whole amount of charge q per unit area A. Hence, the Surface charge density formula is given by, σ = q / A.

Answer 2

hilu mate..❤️

refer to the attachment pls

Let R = 6.4 × 106 m σ = surface charge density Total charge on the surface of earth = q Then, the potential V at a point on the earth’s surface is same as if the entire charge q were concentrated as its centre.
