Apositive test charge of 5.0×10^-6 c is in a mood and electric field that exerts a force of 2.0×10 ^-4 on it what is the magnitude of the electric field at the location of the test charge?

Akg a of 55 m at an of 11 ? . if is at 98 km/h,be ?

Polly is pushing a box across the floor with a force of 30 n. the force of gravity is –8 n, and the normal force is 8 n. which value could describe the force of friction if polly could not move the box?

Along the line connecting the two charges, at what distance from the charge q1 is the total electric field from the two charges zero? express your answer in terms of some or all of the variables s, q1, q2 and k =14ï€ïµ0. if your answer is difficult to enter, consider simplifying it, as it can be made relatively simple with some work.
