An oil drop has `8.01xx10^-19`C charge calculate the number of electrons in this drop.

In Millikan's experiment, static electric charge on the oil drops has been obtained by shining X-rays. If the static charge on the oil drop is -1.282xx10^(-18)C , calculate the number of electrons present on it.

What is the number of electrons in1C charge?

The number of electrons in 2 C of charge is

A body has -0.8 xx 10^(-18) C charge. What is the number of excess electrons in the body?

A body has -80muC charge. What is the number of excess electrons in the body?

The amount of charge present in a charged body is 3.2xx10^(-17)C . If the charge of an electron be e=-1.6xx10^(-19)C , then calculate the number of deficit of electrons in that body.

Copper has 8.0xx10^(28) conduction electrons per metre^3 . A copper wire of length 1m and cross sectional area 8.0xx10^(-6) m^2 carrying current and lying at right angle to a magnetic field of strength 5xx10^(-3) T experiences a force of 8.0xx10^(-2)N . Calculate the drift velocity of free electrons in the wire.
