Question

90 4Uo 7, V- 001 (part 1 of 3) 10.0 points Assume: An electric field set up by an un- known charge distribution 9. More information is needed Uo is the amount of work needed to bring a point charge of charge in from infinity to a point P 10. V- Uo 003 (part 3 of 3) 10.0 points If the charge qo is returned to infinity, how much work W would it take to bring a new charge q = 4q0 from infinity to point P? If point P in Part 1 is at a distance a along the r-axis, how much work W would it take to bring the chargeto a point P, at a distance 4 a along the r-axis? 1. More information is needed 1, W = 0 2° W = U 3° W210 0 4, W= 4, W = 4U0 5. The correct answer is not given. Uo 7. More information is needed 9.W_0 10. The correct answer is not given Uo 10. W = 002 (part 2 of 3) 10.0 points What is the electric potential V at point P? 2, V = 0 3. The correct answer is not given

Explanation / Answer

option 7 : more information is needed is correct.

reason.: we are given with only one test charge q0 and one potential. to calculate the amount of workdone, we need another charge or potential at 4a.
