What is the magnitude of a point charge which produces an electric field of $2\mathrm{N}/\mathrm{coulomb}$ at a distance of $60cm(1/4\pi\epsilon_0 = 9 \times 10^9 \mathrm{N} \cdot \mathrm{m}^2/\mathrm{C}^2)$
Text Solution
Verified by ExpertsThe correct answer is:
A
$E = \frac{1}{4 \pi \epsilon_0} \cdot \frac{Q}{r^2}$
⇒ ⇒ $2 = 9 \times 10^{9} \times \frac{Q}{(0.6)^{2}}$ ⇒ ⇒ Q = 8 × × $10^{-11} C$
