Explanation: Flux is positive when the angle is less than 90°.
38 The formula for the electric flux through the surface of a sphere due to a charge “+q” at its center is ______:
Correct Answer: A
Explanation: Gauss's law states that the flux through a closed surface is $\frac{q}{\epsilon_0}$.
39 According to ______ law, “The total electric flux through a closed surface is equal to the product of ______ and charge enclosed in the surface.”
Correct Answer: B
Explanation: Gauss's law relates electric flux to the enclosed charge.
40 The formula for Gauss’s law is ______:
Correct Answer: A
Explanation: Gauss's law is given by $\phi_e = \frac{Q}{\epsilon_0}$.
41 The work done in moving a unit positive charge from one point to an other point against an electric field is called ______:
Correct Answer: B
Explanation: Potential difference is the work done per unit charge against the electric field.
42 The work done in moving a unit positive charge from infinity to that point against the electric field intensity is called ______:
Correct Answer: A
Explanation: Absolute potential is the work done to bring a unit charge from infinity to a point.
