A glass sphere with radius 4.00 mm, mass 65.0 g, and total charge 3.00 µC is separated by 150.0 cm from a second glass sphere 2.00 mm in radius, with mass 275.0 g and total charge −5.00 µC. The charge distribution on both spheres is uniform. If the spheres are released from rest, what is the speed of each sphere the instant before they collide?

Why is it important always to use horizontal bars in unit fractions when performing unit conversions?
