If 10 power 9electrons move out of body to another body every seconds. How much time is required to get a total charges of 1 C on the other body? |
| Answer» SOLUTION :In one second `10^(@) `electrons move out the body. Thereofore ther CHAGES given out in second is ` 1.6 xx 10 ^(-19) xx 10 ^(@) C. `The time requiredto accumulatea charges of 1 C can then be estimated to be ` 1C + ( 1.6 xx 10^(-10) C//s)= 6.25 xx10 ^(9)s = 6.25 xx 10 ^(9) +( 365xx 24xx 3600)` years = 198 years.Thus to collecta charges of one coulomb from ABODY from which `10^(9) `electrons move out very seconds. we will need approximately200 years. | |
