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...

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...
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...
