We know that a spherical charged particle of will have an external electric field of E = k q/r2, where k = 8.988×109N·m2·C-2 is the Coulomb constant, q is the charge, and r is the distance from the center of the spherical particle. Calculate the electric field (a) for a particle with a charge of q1 = 9.15nC and at a distance of r1 = 4.84m away from the center of the particle, and (b) for a particle with a charge of q2 = 4.95nC and at a distance of r2 = 4.13m away from the center of the particle.
A uniform plank of length 4.30 m and weight 226 N rests horizontally on two supports, with 1.10 m of the plank hanging over the right support (see the drawing). To what distance x can a person who weighs 437 N walk on overhanging part of the plank be..
What percentage of error in would be made if the moment of inertia of the pulley were avoid? Ignore friction in the pulley bearings.
There is an electric field of 113N/C directed along the + x axis. If the string makes an angle 26 degrees with the y axis when the sphere is in stability, what is the charge on the sphere.
What is mechanical energy dissipated by resistive forces
What is the (a) magnitude and (b) angle (measured relative to the positive direction of the x axis) of the asteroid's acceleration.
A 1600 kg submarine rises straight up towards the surface. Seawater exerts both an upward buoyant force of 16430 N on the sub, with a downward resistive force of 1000 N. What is the submarine's acceleration.
