Please try to explain also.

There is a balloon charged with q = +2 C of charge. It is attracted with a force of F = 0.5 N to a negatively charged scarf that is d = 2m away. A. What is the net charge on the scarf? B. What is the Electric-field midway between the scarf and the balloon? (Magnitude and Direction) C. Does the Scarf contain more protons or electrons? How many more? D. How would the attractive force change if the scarf were 10 m away instead of 2m? E. If an electron were placed midway between the balloon and scarf what force would it experience? What acceleration? (magnitude and direction) F. What is the Electric Field strength at the location 4 m from the Balloon and 2 m from the scarf? G. If I place a neutrally charged object next to the balloon would it experience a force? Why or why not
