A spherical cavity of radius 4.31 cm is at the center of a metal sphere of radius 15.0 cm. A point charge Q = 5.84 uC rests at the very center of the cavity, whereas the metal conductor carries no net charge. Determine the electric field at a point 3.06 cm from the center of the cavity.
A steam catapult launches a jet aircraft from the aircraft carrier John C. Stennis, giving it a speed of 190 mi/h in 2.00 s. (a) Find the average acceleration of the plane. Your response is within 10% of the correct value. This may be due to round..
