Question

An electron above the earth is balanced by the gravitational force and the electric field of the earth. Find the electric field of the earth.​

Answer 1

Answer:

E=9.1×10×(-31)×9.8/1.6×10×(-19)

or

E= 568×10×(-11 ) N/C

Explanation:

Under equilibrium condition

electric force due to the earth acting upwards=gravitational force acting downwards

so,

qE = mg

or

E = mg/q

here,

q=e=1.6×10-19 c

m=9.1×10-31 kg

g=9.8m/s²

so

E= 9.1×10×(-31)×9.8/1.6×10×(-19)

or

E = 5.68× 10 to the power (-11) N/C
