Refer the figure to get the distances between charges.
 
Force on -10μC charge due to other charges is = [ 1/(4πε0) ] { (250/425) + (30/185) + (150/25) }×104×10-12 
Sustitute for 1/(4πε0) = 8.99 × 109 in above calculation, we get net attractive force on  -10μC charge = 607 Newtons

CBSE 12-science - Physics
The number of moles in an elemental sample is just the ratio of the mass m to atomic mass 4. n= A The number of protons N, in an elemental sample is Z (atomic number) times the number of moles of Avogadro's number NA N=ZnN P A Copper has an atomic mass of 63.5 g/mole and 29 protons per atom. If such an atom were neutral, then it would have as many protons as electrons. If you remove electrons from a neutral state, then you get a net positive charge. Given a 54 gram ball of copper with a net charge of 2.2 µC, what fraction of the copper's electrons have been removed?
