Two positively charged small particles, ...

Two positively charged small particles, each of mass `1.7 xx 10^(-27) kg` and carrying a charge of `1.6 xx 10^(-19) C` are placed apart at a separation r. If each one experiences a repulsive force equal to its weight find their separation. [0.117 m]

Text Solution

Verified by Experts

`F=(Q_(1)Q_(2))/(4pi epsilon_(0)r^(2))`
`1.7xx10^(-27)xx9.8=(9xx10^(9)xx(1.6xx10^(-19))(1.6xx10^(-19)))/(r^(2))`
`:.r=0.117` m
