If Q2 and Q3 are separated by a distance of 20 cm and have the same charge of 50μC, what is the magnitude of the force between them?
Two parallel straight wires 10.0 cm apart carry currents in opposite directions. Current I1 = 5.0 A is out of the page, and I2 = 7.0 A is into the page. Determine the magnitude and direction of the magnetic field halfway between the two wires.
Consider a solenoid with an air core, with 3000 loops, with a measure of 70 cm, and with a diameter of 3 cm. If a 6 A current is sent through it, how much is the value of the magnetic formed within it?
9. A ball is dropped from a window and hits the ground with a speed of 25 ft/s. How high above the ground is the window?
What is the magnitude of an electric field that exerts a force of 5.0×10^-4N on a charge of 1.0 uC?
If a 5-kg steel plate is attached to one end of a 0.1m x 0.3m x 1.2m wooden pole, what is the
length of the pole above the water? Use density of wood 0.50. Neglect buoyant force on steel.
A long jumper leaves the ground at an angle of 20.0° to the horizontal and at a speed of 11.0 m/s.
a. How long does it take for him to reach maximum height? b. What is the maximum height?
c. How far does he jump? (Assume his motion is equivalent to that of a particle, disregarding the motion of his arms and legs.)
A bartender slides a beer mug at 1.50 m/s toward a customer at the end of a frictionless bar that is 1.20 m tall. The customer makes a grab for the mug and misses, and the mug sails off the end of the bar.
a. How far away from the end of the bar does the mug hit the floor?
b. What are the speed and direction of the mug at impact?
A boy on top of a hill thrown a stone with an initial velocity of 100ft/sec at an inclination of 60° with the horizontal. If the stone has travelled a distance on 400ft from the base of the hill, how high is the hill?
