Four solid plastic cylinders all have radius 2.75 cm and length 6.42 cm. Find the charge of each cylinder given the following additional information about each one. Cylinder (a) carries charge with uniform density 16.1 nC/m2 everywhere on its surface. Cylinder (b) carries charge with uniform density 16.1 nC/m2 on its curved lateral surface only. Cylinder (c) carries charge with uniform density 490 nC/m3 throughout the plastic. Cylinder (d) carries charge with uniform linear density 63.4 nC/m along the length of the plastic. All answers are in Coulombs.
A 4.5 box slides down a 4.7 high frictionless hill, starting from rest, across a 1.6- -wide horizontal surface, afterwards hits a horizontal spring with spring constant 550 . The other end of the spring is anchored against a wall. The ground under..
A 100-turn square wire coil of area 0.04m2 rotates about a vertical axis at 1500 rev/min, as indicated. The horizontal component of the Earth's magnetic field at the location of the loop is 2.0 × 10-5 T. compute the maximum emf induced in the coil..
