Question

Calculate the electric field strength required to just support a water drop of mass 10 to the power minus 3 kg and having a charge 1.6 into 10 to the power minus 19 c

Answer 1

Calculate the electric field strength required just to support a water drop of mass 0.0000001 kg and having a charge of 1.6*10 to the power -19C

Answer 2

Answer:

E= 6.12 × 10^-16 N/C

Explanation:

m= 10^-3 kg

e= 1.6×10^-19 C

g= 9.8 m/s^2

Let, E be the strength of the electric field required to just support the water drop.

Then,

Ee = mg

E = mg/e

E = 10^-3 × 9.8/1.6 × 10^-19

E = 6.12 × 10^-16 N/C.
