Question
1. A metal ball has -9 Coulomb of charge. If it receives 0.50 * 10^20 number of electrons, what will be the resultants charge of the ball? 2. 2 equal charges are seperated by 33 mm and experiences a repulsion force of 9 Newton. Calculate the amount of each charge in micro Coulombs. 3. 2 equal charges, 147 micro Coulombs each, experiences an attraction force of 147 Newton. Calculate the distance between the charges in mm. 4. Add 6 micro Coulombs and 4,743 nano Coulombs and get the results in nano Couloms unit. PLEASE TYPE IN RESPONSE AND NOT UPLOAD PICTURE! Thnx 1. A metal ball has -9 Coulomb of charge.

1.
n = number of electrons = 0.50 x 1020
e = charge on an electron = -1.6 x 10-19 C
Total charge due to electron is given as ::
Qe = ne
Qe = (0.50 x 1020) (-1.6 x 10-19)
Qe = -8C
Total charge on metal ball = - 9 C + (-8C) = -17 C
