The electric field strength re-quired to just support a water dropof mass 107kg and having charge1.6 x 10-T9 C is19ーナ1) 6125 × 1012 NC" s-12-2) 61.25 x 10-12 NC-16.125 × 10-12 NC-14) of these |

Answer» Force due to electric field = Weight of water dropEq = mg E = mg/q= (10^-7 kg × 9.8 m/s^2) / (1.6 × 10^-19 C)= 6.125× 10^12 N/C ∴ Electric field strength required is 6.125× 10^12 N/C nice answerrrrrr........... |
