Two identical particles, each having a charge of `2.0xx10^(-4) C` and mass of 10g are kept at 10cm and then released. What would be the speeds of the particles when the separtion becomes large?

Explanation

` m=10g, f=1.8xx10^4 `
` f=mxxa `
` rArr a=1.8xx10^6m//s^2 `
` We have, `
` v^2=v^2+2as `
` v^2=0+2xx1.8xx10^6xx10xx10^-2 `
` v=sqrt(36xx10^4)=6xx10^2m//s `
` =600m//s`
