To determine the volume of a sphere, you measure its diameter using a ruler an obtain a value of 15.2 mm for the diameter. Using this diameter, you convert the diameter to units of centimeters by dividing the radius by 10 mm/cm and then you divide the diameter by 2 to obtain the radius (r). You then use the equation V = 4/3rr to obtain the volume of the sphere. To determine the mass, you measure the mass on a...

A glass sphere with radius 4.00 mm, mass 55.0 g, and total charge 2.00 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? v1=? v2=?
