Electrostatics Question 407

Question: Electric field strength due to a point charge of $5 μ C$ at a distance of 80 cm from the charge is [CBSE PMT 2000]

Options:

A) $8 \times 10^{4}$ N/C

B) $7 \times 10^{4}$ N/C

C) $5 \times 10^{4}$ N/C

D) $4 \times 10^{4}$ N/C

Show Answer

Answer:

Correct Answer: B

Solution:

$E = 9 \times 10^{9} . \frac{Q}{r^{2}}$
