In a 1.25-T magnetic field directed vertically upward, a particle having a charge of magnitude 8.50 µ.C and initially moving northward at 4.75 km/s is deflected toward the east.
(a) What is the sign of the charge of this particle? Make a sketch to illustrate how you found your answer.
(b) Find the magnetic force on the particle.
A certain superconducting magnet in the form of a solenoid of length 0.30 m can produce a magnetic field of 13.0 T in its core when its coils carry a current of 105 A. The windings, made of a niobium-titanium alloy, must be cooled to 4.2 K. Find o..
The plates of a parallel-plate capacitor each have an area of 0.1 m2 and are separated by a 0.6 mm thick layer of paper. The capacitor is connected to a 13 V battery. (The dielectric constant for paper is 4.)
Each shot of the laser gun most favored by Rosa the Closer, the intrepid vigilante of the lawless 22nd century, Find the electric potential energy of the original capacitor when it is charged
The coefficient of static friction between the ladder and the ground is 0.55, and the ladder makes a 50.0° angle with the ground. Explain how far up the ladder can an 870 N person climb before the ladder begins to slip?
Suppose we move along the+y-axis from ya= 0.0 m (where the potential is 2000V) to yb = 2.0 m. Alongthe yaxis in this region, the electric field has amagnitude given by (1200 V/m4)y3 and makes an angle of 60° withthe+y-direction. Find the potential..
To focus a camera on objects at different distances, the converging lens is moved toward or away from the film, so a sharp image always falls on the film. Over what distance must the lens be movable
Neutron stars, such as the one at the center of the Crab Nebula, have about the same mass as our sun but a much smaller diameter. If you weigh 660N on the earth, what would be your weight on the surface of a neutron star that has the same mass as ..
A truck of mass 9312 kg moving at a speed of 68.7 mph has lost its brakes. How far along the incline (?x) does the truck travel before it stops
A 0.700-kg ball is on the end of a rope that is 0.90 m in length. The ball and rope are attached to a pole and the entire apparatus, What is the tangential speed of the ball
Consider a rotational axis at point where the tire contacts the ground, directed vertical to the plane of the paper. Find out the magnitude of the man's force for both designs.
A 94.0 cm pendulum is released from a small angle. After 113 oscillations the amplitude is one half of its original value. The damping is proportional to the speed of the pendulum bob. Find the value of the damping coefficient, ?, (in Hz).
