1. The problem statement, all variables and given/known data Two tiny conducting spheres are identical and carry charges of -19.4 μC and +49.3 μC. They are separated by a distance of 2.55 cm. What is the magnitude of the force that each sphere experiences? 2. Relevant equations Coulombs Law: F=kelq1q2l/r2 Ke = 8.99E9 3. The attempt at a solution The way I write down the numbers is how I put them into my calculator. F=((8.99E9)(-19.4E-6)(49.3E-6)) / ((2.55E-2)2) F= -8.5982158 / 6.5025E-4 F=-13222.9385 but magnitude cant be negative so it would be F= 13222.9385 N I am not sure what I am doing wrong. I have tried multiple tries at reworking/entering the problem into the calculator to see if I'm somehow messing it up, however I keep getting the same answer. F=[((-19.4E-6)(49.3E-6)) / ((2.55E-2)2)] * (8.99E9)= 1.47084967E-6 * (8.99E9) = 13222.9385 N F=(8.99E9)(-19.4E-6)(49.3E-6) = -8.5982158 ; (2.55E-2)2 =6.5025E.4 ; F= -8.5982158 / 6.5025E.4 = 13222.9385 N Help would be greatly appriciated!
