Homework Statement A. what would happen if the Earth suddenly stopped spinning B. what would happen if the Earth lost it's gravitational pull Homework Equations The Attempt at a Solution these are some ideas i have, can you tell me if they are correct or not, and some ideas you may...

Homework Statement Capacitors of 11.1uF and 1.9uF are charged as a parallel combination across a 333V battery. The capacitors are disconnected from the battery and from each other. They are then connected positive to negative plate and negative to positive plate. Find the resulting charge on...

well that is just aggravating. i had the decimal in the wrong place on 3 of those 4 times i got it wrong. it is correct now. thank you! where i went wrong was with the area. it is 8.39e-4 instead of 8.39e-2 (going from cm to m) because it's two dimensions, right? once again, thank you.

Willem: i had used 12.3e-3 because part A of the question asked for the electric field between the plates in kV/m, which 15.185 was the answer. i tried doing this part with 12.3v for the whole thing and it still came out wrong. rl.bhat: i also tried C=E0A/d E0 being permittivity constant...

Homework Statement An air filled capacitor consists of two parallel plates, each with an area of 8.39cm^2, separated by a distance of .81mm. A 12.3V potential difference is applied to the plates. Find the capacitance. Answer in units of pF (pico Farad) Homework Equations 1. E = kV/d 2...

yes it would be. thank you

awesome! thank you.

the area of a circle is pi*r^2...but this is a loop...or are they the same thing?

i see that i completely overlooked the equation of flux = q/Eo (permittivity of free space)...that's the right equation right? the flux will be 4680.26 correct? thanks!

Homework Statement a point charge of .04144 uC (micro C) is inside a pyramid. determine the total electric flux through the surface of the pyramid in units Nm^2/C Homework Equations The Attempt at a Solution i really don't know, i don't feel like there is enough information given.

Homework Statement a 29 cm diameter circular loop is rotated in a uniform electric field until the position of maximum electric flux is found. the flux is measured to be 7.2e5 Nm^2/C what is the electric field strength in units N/C? Homework Equations flux = EA The Attempt at a...

thank you! that worked.

Homework Statement postively charged bead having a mass of .61g falls from rest in a vacuum from a height of 5.9 m in a uniform vertical electric field of magnitude 11600 N/C. The bead hits the ground at a speed of 19 m/s. acceleration of gravity is 9.8 m/s^2. find the charge on the bead...
