An electron of mass `9.1xx10^(-31)` kg is at a distance of `10 A^(@)` from a. porton of mass `1.67xx10^(-27)` kg. calculate the gravitational force of attraction between them.

Explanation

Here, `m_(1)=9.1xx10_(-31) kg, d=10A^(@)=10^(-9)m`
`M_(2)=1.67xx10^(27)kg, F=?`
`F=(Gm_(1)m_(2))/d^(2)=(6.67xx10_(-11)xx9.1xx10^(-31)xx1.67xx10^(-27))/(10^(-9))^(2)=1.01xx10^(-49)N`
