Question

a polythene piece is rubbed with woolen cloth as a result 4.8×10^-7 c . charge is produced in it . what will be the no of electrons transfered from wool to polythene ? calculate the increase in mass of polythene . ( mass of 1 electron = 9.1×10^-31​

Answer 1

Answer:

plz follow me

Explanation:

When polythene is rubbed against wool, a number of electrons get transferred from wool to polythene. Hence, wool becomes positively charged and polythene becomes negatively charged. Therefore, the number of electrons transferred from wool to polythene is 1.87 × 1012.
