Question

5 There are 6 piOU 6. For the problems draw a box afU However, to get credit for any answer y r you need MULTIPLE CHOICE QUESTIONS 1) Two small charged objects othe distance d. If the charges same s repel each other with a force F when separated by a remain the same and the distance between them is redtuced dis the force becomes B) 3F E) 27F 2) The diagram sh charged spheres (Y and Z). Then ows the electric field lines in a region of space containing two small A) Y is negative and Z is positive B) the magnitu de of the electric filed is the same everywhere the electric field is strongest midway between Y and Z D))Y is positive and Z is negative Y and Z must have the same sign

Explanation / Answer

1) F = kq1q2 / r^2

so when the distance is reduce to 1/3 , The force will be 9 times

so 9F

2) for a positive charge , EF lines move out and negative charge EF line moves in

so option D) Y is positive and Z is negative
