I need help with this problem. What is the magnitude and direction of the elctric force on a -1.2 micro Coulomb charge at a point where the electric field is 2500 N/C and is directed along the +y axis? It has something to do with this equation: F=k_e \frac {Q_1 Q_2} {r^2} I got 0.15 N...

Can anybody confirm with me for the first question I posted? Thanks.

Oh yes, Volume is directly proportional to Temperature in this case, Thanks. 3 times the Volume then.

A certain kind of glass n_blue = 1.650 for blue light and n_red = 1.610 for red light. If a beam of white light (containing all colors) is incident at an angle of 30.0 degrees, what is the angle between the red and blue light inside the glass? I use the Snell's equation...

Did you use the 2nd right hand rule for the last question?

Hey all, I have some hard times with these critical thinking questions. Please help me out. Thanks. 1. The magnitude of the electric field at a point in space does not depend upon... a. The distance from the charge causing the field. b. The sign of the chrge causing the field. c. The...
