Suppose all the electrons of 100 g water are lumped together to form a negatively charged particle and all the nuclei are lumped together to form a positively charge particle. If these two particles are placed 10.0 cm away from each other, fien the force of attraction between them. Compare it with your weight.

Explanation

No. of electrons in `100 gm H_2O`
` =3.34xx10^25 `
and total charge of electron in `100 gm`
` water=-5.34xx10^6C `
Similarly, Total charge of protons in `100 gm=+5.34xx10^6C `
Hence electrical force
` =9xx10^9xx(5.34xx 10^6xx5.34xx10^6)/10^-2 `
` =2.56xx10^25 Newtons`
