An alpha particle (the nucleus of a helium atom formed by 2 protons and 2 neutrons with charge q = +2(1.6 x 10-19 C ) is moving perpendicular to a magnetic field of 0.730 teslaat a velocity of 3.30E+6 m/s ; calculate the magnitude of the magnetic force exerted on it.
Calculate the acceleration of the alpha particle.
What will be the radius of curvature of the path followed by the alpha particle in the magnetic field?
What would be the force on the alpha particle if it were traveling parallel to the magnetic field lines?
A chair of weight 130 N lies atop a horizontal floor; the floor is not frictionless. You push on the chair with a force of F = 43.00 N directed at the angle of 35.0 degrees below the horizontal and the chair slides along the floor. Using Newton's law..
A parachutist with a camera, both descending at a speed of 11 m/s, releases that camera at an altitude of 140 m. Explain how long does it take the camera to reach the ground?
What is the speed of the two carts at the moment while their speeds are equal.
A thin, circular disc is made of lead and has a radius of 0.0350 cm at 20.0 °C. find out the change in the area of the circle if the temperature is increased to 625.0 °C. The coefficient of linear thermal expansion for lead is 29.0 x 10-6/C°.
What is the net electric force acting on particle.
In NYU's Diffraction and interference lab for general physics 2, what are the widths given on the slide with the double slits. On the lab manual it says they were given on the slide.
Sketch a force diagram for the desk.
A 45.50 cm diameter disk rotates with a steady angular acceleration of 2.00 rad/s2. It starts from rest at t = 0, and a line drawn from the center of the disk to a point P on the rim of the disk makes an angle of 57.30° with the positive x-axis at..
A 10.00 kg grocery is pushed 12.0 m along an aisle by a shopper who exerts a constant horizontal force of 40.0 N. a.) What work is done on the cart? b.)If all frictional forces are neglected, and the cart starts form rest, what is the grocery cart..
Charge Q = 10E-8 C is placed in the origin. Location A is -3.00m from the charge while location B is 2.00m from the charge. A) Find the potential difference VB - VA between the two points. B) Which point is at the higher potential? Type either "Po..
Two circus performers, Jack and Jill, whose total mass is 120 kg, start a swing which is 5 m long such that initially the rope attached to their swing makes an angle of 36 degrees with the horizontal.
A cop car drives at 30m/s toward the scene of a crime, with its siren sounding (f = 2125 Hz.) Estimate the frequency heard by people at the crime scene as the siren approaches and the frequency heard as the siren moves away from people.
