I tried 55, and it didn't work. Is electrical flux supposed to be negative? Thats all I can think of. I don't know if that's right.

I used the formula (E * Area * cos(theta)) and got the wrong answer (.02529) and I really don't understand why. I need help The square surface shown measures 4.0 mm on each side. It is immersed in a uniform electric field with magnitude E = 1930 N/C. The field lines make an angle of 35° with...

If your answer is .0026162 N that isn't correct either. I don't really know how to show the calculations here though.

+q -a- -q | | a a | | +2q -a- -2q What are the horizontal and vertical components of the resultant electrostatic force on the charge in the lower left corner of the square if q = 0.9 10-7 C and a = 4.4 cm? (Assume the positive directions are...

Can someone explain this: For question A I originally got around .142 M, but that was apparently wrong, because I assumed the phase constant was zero. Can someone explain what the phase constant is and how to find it? A simple harmonic oscillator consists of a block of mass 2.60 kg...

I need some help, I've never dealt with a torque problem that uses friction or mechanical energy. This is the problem: Attached to each end of a thin steel rod of length 1.00 m and mass 6.70 kg is a small ball of mass 1.10 kg. The rod is constrained to rotate in a horizontal plane about a...

nevermind I figured it out

When I try to solve for V3 in that equation I keep getting the square root of a negative number...

So the sum of the energy and momentum has to equal zero? Since the initial kinetic energy was zero?

I need some help on how to solve this question, I don't really know how to do this at all. A vessel at rest explodes, breaking into three pieces. Two pieces having equal mass, fly off perpendicular to one another with the same speed of 30 m/s. The third piece has three times the mass of each...
