The electric field intensity just sufficient to balance the earth’s gravitational attraction on an electron will be: (given mass and charge of an electron respectively are `9.1xx10^(-31)kg` and `1.xx10^(-19)C)`

The charge on 1 microgram (g) electron will be......(mass of an electron = 9.11 xx 10^(-31) kg)

Calculate the change in mass of an object if 800 electrons are given to it Given: Mass of an electron is 9.1xx10^(-31) kg .

Consider the charge configuration as shown in the figure . Calculate the electric field at point A. If an electron is placed at points A, what is the acceleration exerienced by this electron? (mass of the electron =9.1xx10^(-31) kg and charge of electron =-1.6xx10^(-19)C).

Calculate the electric field intensity E which would be just sufficient to balance the wight of an electron. If this electric field is produced by a second electron located below the first one what would be the distance between them? [Given: e=1.6xx10^(-19)C, m=9.1xx10^(-31)kg and g=9.8 m//s^(2) ]
