India Study Solution Objective Questions Test Series
Set 4 (Q. No 31-40)

Question 31: Consider the situation of figure (29-Q3). The work done in taking a point charge from P to A is WA, from P to B is WB and from P to C is WC.

a. WA< WB< WC

b. WA> WB> WC

c. WA = WB = WC

d. None of these

Question 32: When a glass rod is rubbed with silk, it:

a. gains electrons from silk

b. gives electrons to silk

c. gains protons from silk

d. gives protons to silk

Question 33: Two point charges of same magnitude and opposite sign are fixed at points A and B. A third small point charge is to be balanced at point P by the electrostatic force due to these two charges. The point P -

a. lies on the perpendicular bisector of line AB

b. is at the mid-point of line AB

c. lies to the left of A

d. none of these

Question 34: In a certain region of space where electric potential is constant, the magnitude of electric field is

a. Also constant

b. Positive

c. Negative

d. Zero

Question 35: Relative permittivity of mica is:

a. one

b. less than one

c. more than one

d. infinite

Question 36: Potential due to a charged conducting shell varies as inversely proportional to the distance from its centre at

a. Inside the sphere

b. Outside the sphere

c. Only outside the sphere

d. Does not vary like mentioned

Question 37: The electric field above a uniformly charged non conducting sheet is E. If the non-conducting sheet is now replaced by a conducting sheet, with the charge same as before, the new electric field at the same point is:

a. 2E

b. E

c. E/2

d. None of these

Question 38: The wrong statement about electric lines of force is

a. These originate from positive charge and end on negative charge

b. They do not intersect each other at a point

c. They have the same form for a point charge and a sphere

d. They have a physical existence

Question 39: A negative charge is placed at some point on the line joining the two +Q charges at rest. The direction of motion of negative charge will depend upon the:

a. position of negative charge alone

b. magnitude of negative charge alone

c. both on the magnitude and position of negative charge

d. magnitude of positive charge

Question 40: If we move in direction opposite to the electric lines of force:

Hints and Solutions of Physics Electrostatics MCQ Test Series – Set 4 (Q. No.31–40)

Answer 32: b (Hint: When we rub glass rod with silk, excess electrons are transferred from glass to silk. So, glass rod becomes positive and silk becomes negative).

Answer 33: d (Hint: There is no point near electric dipole having E = 0).
