Since the spheres are small so can be considered as point charge
F=kq1.q2/r²
F=(9x10^9).(2x10^-7).(3x10^-7)/(0.3)²
F=18 x 10¯³N
Hope it helps you

Q1=2*10^-7 C
Q2=3*10^-7 C
R=30CM, =30/100 M
K=9*10^9 NM^2/KG^2
F=KQ1Q2/R^2
=9*10^9*2*10^-7*3*10^-7/(30/100)^2
=9*6*10^-5/(30*30/100*100)
=9*6*10^-5/(3*3/10*10)
=9*6*10^-5*100/3*3
=9*6*10^-3/3*3
=9*2*10^-3
=18*10^-3 N
Q2=3*10^-7 C
R=30CM, =30/100 M
K=9*10^9 NM^2/KG^2
F=KQ1Q2/R^2
=9*10^9*2*10^-7*3*10^-7/(30/100)^2
=9*6*10^-5/(30*30/100*100)
=9*6*10^-5/(3*3/10*10)
=9*6*10^-5*100/3*3
=9*6*10^-3/3*3
=9*2*10^-3
=18*10^-3 N
my pleasure solving it!
