Electrostatics Question 679

Question: Two insulated charged metallic sphere P and Q have their centers separated by distance of 60 cm. The radii of P and Q are negligible

Options:

A) 5.2×104N

B) c 2.5×103N

C) 1.5×103N

D) 3.5×104N

Show Answer

Answer:

Correct Answer: B

Solution:

[b] Here q1=q2=3.2×107c,r=60cm=0.6m

Electrostatic force, F=14πε0q1q2r2

=3×109(3.2×107)2(0.6)2=2.56×103N
