(b) The soheres are brought ita contact and then separated to adistance ot 2.86 om. Detenmine the magnibude of ehe force ehat eaoh sonere no pennc 8 5

Explanation / Answer

(a) F=kQ1Q2/r^2
where k=Coulomb constant 8.99x10^9 N m^2 /C^2. Remember to convert r from cm to m.

F=9*109*24.8*48.9*10-12/(0.0286)2

F=13343.537N

(b) total charge is shared equally between the two spheres: Q3=(Q1+Q2)/2=(-24.8+48.9)/2.

Q3=12.05 uC
F=kQ3Q3/r^2.

F=1597.66 N
