Answer:
B C & D
Explanation:
should make you money, time well spent no time lost.
As we know by Gauss's law that

so for line charge the gaussian surface is cylindrical in shape
so we will have

now by rearranging the terms

so here we will have to find the x component of electric field so it is given by above equation

here x = distance from the wire where we need to find electric field
Answer:

Explanation:
The electric force between two charged objects is given by:

where:
k is the Coulomb's constant
q1 and q2 are the charges of the two objects
r is their separation
In this problem:
q1 = 2.0 C
q2 = 1.0 C
r = 2 m
So, the electric force is

Answer:
Yes
