A charge of 3.45 µC is uniformly distributed on a ring of radius 9.5 cm. Find the electric field strength on the axis at the following locations. (a) 1.2 cm from the center of the ring N/C (b) 3.1 cm from the center of the ring N/C (c) 4.0 m from the center of the ring N/C (d) Find the field strength at 4.0 m using the approximation that the ring is a point charge at the origin. N/C (e) Compare your results for parts (c) and (d) by finding the ratio of the approximation to the exact result.
Determine the time it takes for the particle. A particle is traveling in a straight line at a constant speed of 28m/s. Suddenly, a constant force of 15.6N acts on it, bringing it to a stop in a distance of 66.8m.
A wrench 0.3 meters long lies along the positive y-axis, and grips a bolt at the origin. A force is applied in the direction of langle 0, 1, 2rangle at the end of the wrench. Find out the magnitude of the force in newtons needed to give 100 newton..
What is the electrostatic force on each particle.
A bicycle wheel is rotating at 45 when the cyclist begins to pedal harder, giving the wheel a constant angular acceleration of 0.42.
A projectile is launched straight up at 59 m/s from a height of 73 m, at the edge of a sheer cliff. The projectile falls, just missing the cliff and hitting the ground below.
Compute the distance of two point's p1 and p2 in the x-y plane with the following Cartesian coordinates: p1= (-5m, +8m), p2= (+3m, +2m). Draw the position vectors into appropriate-points.
Four particles with masses 4 kg, 2 kg, 4 kg, and 2 kg are associated by rigid rods of negligible mass. The origin is centered on the mass in the lower left corner, and all the particles are located in Quadrant 1. The rectangle is 5 m wide and 4 m ..
Two equally charged, 1.00 {rm g} spheres are placed with 2.00 {rm cm} between their centers. When released, each begins to accelerate at 225 {rm m/s^2}. What is the magnitude of the charge on each sphere.
It has been suggested that rotating cylinders about 12 mi long and 5.1 mi in diameter be placed in space and used as colonies. What angular speed should such a cylinder have so that the centripetal acceleration at its surface equals free-fall acce..
A 200 km long high-voltage transmission line 2 cm in diameter carries a steady current of 1050 A. If the conductor is copper with a free charge density of 8.8 x10^28 electrons per cubic meter, how various years does it take one electron to travel ..
