22 If the field charge applies a force $\overline{\text{F}}$ on the test charge $q_0$, then formula for electric intensity is ______:
Correct Answer: A
Explanation: Electric intensity is defined as $\overline{\text{E}} = \frac{\overline{\text{F}}}{q_0}$.
23 The SI unit of electric intensity is ______:
Correct Answer: A
Explanation: The SI unit of electric intensity is newtons per coulomb (N/C).
24 The dimensions of electric intensity are ______:
Correct Answer: C
Explanation: The dimensions of electric intensity are [MLT$^{-3}$C$^{-1}$].
25 The points where the resultant intensity is zero, are called ______:
Correct Answer: B
Explanation: Neutral points are locations where the net electric field is zero.
26 The electric lines of forces start from a positive charge and end on a ______:
Correct Answer: A
Explanation: Electric field lines originate from positive charges and terminate on negative charges.
27 The electric lines of forces can never ______ each other:
Correct Answer: A
Explanation: Electric field lines never intersect as it would imply two directions for the field at one point.
28 The lines of forces are ______ to the surface of the conductor:
Correct Answer: B
Explanation: Electric field lines are perpendicular to the surface of a conductor in electrostatic equilibrium.
