Question: An electrophoresis experiment is performed on two fragments of DNA with radius r1 = 16 nm and charge q1 = -7e, and r2 = 29 nm. The speed of the smaller fragment is two times greater than the speed of the larger fragment.
Part A: What is the charge on the larger fragment? (Non physical fractional charge values WILL be accepted due limitations in the proposed model.)
Please do a step by step solution since I'm kind of lost with this question.
