magnitude of 190.2 V/m, with components Ex = -34.23 V/m and Ey = -155.32 V/m. Oh, I didn't include this numbers before...didn't think they were applicable. Sorry, I'm stuck :( So, E = the above equation for lambda1 + lambda2?

Solved.

Thank you!

Q1 is up and to the left of Q2. Oh, so force must be negative since it's Q2 acting on Q1?

Homework Statement You are at a rock concert, standing 12.1 m from one of the loudspeakers. Based on the pain in your ears, you estimate the decibel level to be about 112 dB at this location. You are worried that this intensity level may be harmful to your ears and result in a degradation of...

So by using T = 2pi * sqrt(m / k) where m = 0.649kg and k = 5.5, I get T = 2.15 Look good? Thanks so much for your help

Ok, so I get k = 5.50 from F = kx Then use T = 2pi*sqrt(m/k) What is gm as a unit of mass?

Sorry, and thanks for your help. How do I solve for the spring constant?

A mass of 361 grams is hung from the bottom of a vertical spring and the spring stretches 64.3 cm. The hanging mass is removed, and the spring is placed horizontally on a frictionless table. One end of the spring is held fixed and the other end is attached to a 649 gm mass. The 649 gm mass is...

I think I have #3 wrong. I believe it is just U. Reasoning: If mass is the same and radius is increasing, density is decreasing. If the density were to decrease only a little tiny bit, the water level would obviously not change. If the density were to decrease as much as possible, it would...

Yep, that was my line of thinking as well...good to hear. Any idea which is/are incorrect?
