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

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

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

Physics Electrostatics MCQ Test Series – Set 4 (Q. No.31–40)
https://www.indiastudysolution.com
Answer 31: c.
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).
