Please explain the term "mechanics and space" and then explain if Mechanics is applicable in Space. My friend says that since there is no atmosphere and gravitation,Mechanics cannot be applied applicable in Space. I know that Mechanics is applicable in Space, but I couldn't make her...

Yes, the original field will be disturbed by the test charge's own field. It is considered that the value of the test charge taken is very low i.e. the minimum value of the test charge is taken so that the disturbance in the original field is minimum and this minimum disturbance...

1 Why do we choose a spherical surface as gaussian surface for a point charge to calculate electric field? In my view, the reason may be i. If we take the point charge at centre, each point of spherical surface will be at same distance from the...

According to the Gauss's Law, Q is the charge inside the gaussian surface. So, the 2nd answer involving 'r' is right.

Please explain the relation between electric potential energy and electric field in detail.
