The intensity of electric field required to balance a proton of mass $1.7 \times 10^{-27} \, \mathrm{kg}$ and charge $1.6 \times 10^{-19} \, \mathrm{C}$ is nearly
Text Solution
Verified by ExpertsThe correct answer is:
A
Since qE = mg or $E = \frac{mg}{q} = \frac{1.7 \times 10^{-27} \times 9.8}{1.6 \times 10^{-19}}$
= 10.0 × × 10 –8 = 1 × × 10 –7 V/m
