Answer #1

We know,

q.E = m.g

here, q = charge of the drop.

E = electric field= 1.715×10^5 N/C

m = mass of the drop = 1.4×10^(-14) kg

g = gravitational acceleration = 9.8 m/s²

Now, q×1.715×10^(5) = 1.4×10^(-14)×9.8

=> q = 8×10^(-19) C

The charge of the drop will be 8×10^(-19) C.

Please comment if you have any doubt and like if it helps.

Happy learning.

    Oil Drop 11. Robert Millikan received a Nobel Prize for determining the charge on the electron. To do this, he set up a of oil between potential difference between two horizontal parallel metal plates. He then sprayed drops the plates and adjusted the potential difference until drops of a certain size between the plates, as shown above. Suppose that when the potential difference adjusted until the electric field is 10,000 N/C downward, a certain drop with a mass of remains...

    In 1909, Robert Millikan was the first to find the charge of an electron in his now-famous oil-drop experiment. In that experiment tiny oil drops were sprayed into a uniform electric field between a horizontal pair of oppositely charged plates. The drops were observed with a magnifying eyepiece, and the electric field was adjusted so that the electric force on some negatively charged oil drops was just sufficient to balance their weight. Millikan accurately measured the charges on many oil...
