A particle of mass 9x10 ^-5 g is kept over a large horizontal sheet of charge density 5x10^-5Cm-2 ? What charge should be to the particle, so that if released it does not fall? in this question solution how we got to know that charge must be positive

Expert Answer:

For the particle should not fall once released, the charge on the particle must be positive  so that the upward force will be exerted on the particle by an electric field.
