1. The problem statement, all variables and given/known data Two spherical objects are separated by a distance of 2.5 x 10-3 m. The objects are initially electrically neutral and are very small compared to the distance between them. Each object acquires the same negative charge due to the addition of electrons. As a result each object experiences an electrostatic force that has a magnitude of 5.75 x 10-3 N. How many electrons did it take to produce the charge on one of the objects. 2. Relevant equations F=(k)[(q1xq2)/r2] coloumbs law F=electrostatic force r=distance k=8.99x10^9 q1/q1=charge on each object 3. The attempt at a solution d=2.5x10^-3 metres (given) F=5.75x10^-3 (given) q1/q2=to be found I changed moved the formula to leave q1/q2 on one side, giving me: r^2(F/k)=(q1)(q2) with values plugged in it boiled down to: 4X10^-18=q1(q2) Since q1 and q2 have the same charge, I figured it'd be fair to say 4x10^-18=q^2 therefore q=square root of (4x10^-18) q=0.000000002 Coloumbs then converted coloumbs to number of electrons giving me and answer of: 1.25x10^10 electrons This is my first attempt of a question on this semester and I'm doing them as I'm going over the lecture notes, did I get it right?
