Can anyone help me with this problem ?
Two positively charged spheres of mass 1 kg each are held in free space, 1 meter away from each other. The two spheres have a charge of 1.0541 × 10^-5C each. One charge is released while the other is still held fixed.
a) Find the speed of the moving charge when it is 2 meters away from the fixed charge.
b) Find the speed of the moving charge when it is 3 meters away from the fixed charge. K = 9 × 10^9Nm^2/C^2
