As you walk across a synthetic-fiber rug on a cold, dry winter day, you pick up an excess charge of -56?C.
Part A How many excess electrons did you pick up?
N =
Part B What is the charge on the rug as a result of your walking across it?
Q =
A spool of thread has an average radius of 1- cm. If the spool contains 62.8 m of thread, how many turns of thread are on the spool.
An explorer in dense jungles of equatorial Africa leaves his hut. He takes 41 steps at an angle 45 north of east, then 81 steps at an angle 60 north of west, then 51 steps due south. Suppose his steps all have equal length. Save him from becoming ..
A 9.00 kg point mass and a 15.0 kg point mass are held in place 50.0 cm apart. A particle of mass m is released from a point between the two masses 19.0 cm from the 9.00 kg mass along the line connecting the two fixed masses.
A 0.100g plastic bead is charged by the addition of 1 x10^10 excess electrons (i.e. so the bead becomes negatively charged). What electric field (magnitude and direction) will cause the bead to hang suspended in the air?
