when a piece of polythene is rubbed with wool, a charge of
2x 10⁷(minus)c is developed on polythene. what is the amount of mass, which is transferred to polythene.​

Answer 1

Answer:

Explanation:

As negative charge is developed on polythene, thus electrons get transferred from wool to the polythene.

Mass of one electron  m  

e

​  

=9.1×10  

−31

 kg

Charge of one electron  q=1.6×10  

−19

C

∴  Mass of  2×10  

−7

C charge,  M=  

q

m  

e

​  

 

​  

×2×10  

−7

   kg    

∴  M=  

1.6×10  

−19

 

9.1×10  

−31

 

​  

×2×10  

−7

=11.38×10  

−19

 kg
