- Two small balls with a mass of 2 g each are hanging on two separate strings 0.5 m (50 cm) long attached to a common point. They are given an identical negative charge and spread apart to a distance 6 cm from each other. How many excess electrons are there on each ball not cancelled by positive charge?Two charged spheres are separated by a distance R. The charges experience a force F. One of the spheres is then replaced with a new sphere that has twice the charge and is a distance of 0.5R away. What is the new force? Question 1 options: 4F 2F 8F Fonly 7 and 8
- Two point charges, q, and q2 , are placed a distance d apart and exert a Coulomb force F on each other. If the distance between the charges is doubled, and q, is replaced with a charge 3q, ,what is the new Coulomb force between the charges?A small metal sphere carrying a net charge of Q = -2.00 uC is held stationary by insulating supports. A second small metal sphere with a net charge of Q 2 = +7.80 uC and mass 1.50 g is is held 0.8 m away from the center of the first sphere. Assume the two spheres can be treated as point charges and that you can ignore gravity. If the second sphere is released, how fast will it be traveling when it is 0.6 m away from the center of the first sphere?please help with questions 28,29,30
