Answer:
3.96*10^-5 Coulombs
Step-by-step explanation:
Given the following charges
Object A = 4.5 x10^-2 Coulombs
Object B = 8.8 x10^-4 Coulombs
Taking their product
A * B = 4.5 x10-2 * 8.8 x10^-4
A*B = (4.5*8.8)*(10^-2 * 10^-4)
A*B = (39.6)*10^-6
A*B = 3.96*10^1 * 10^-6
A*B = 3.96*10^{1-6}
A*B = 3.96*10^-5 Coulombs
Hence the product of their charges is 3.96*10^-5 Coulombs
