One end of the cord is attached directly to the ceiling's rigid support, and the other end is attached to a spring with a constant k=10N/m. When the moon is at point B, the distance from the moon to the center of the planet is most nearly. Two identical charged spheres suspended in air by strings of equal lengths makes angle 30 degree, which is same when they are suspended in liquid with density 0.8 g/cc. 0 is called the permittivity constant 3 When several points charges are present, the total . The meterstick is initially at rest on a horizontal surface and free to move without friction. B Problem: Two identical metal spheres A and B are on their insulator mountings, both initially neutral.

Sphere Y is then brought close to X on the side opposite to the rubber rod. In which configuration is the electric field at P pointed at the midpoint between two of the charges? If air resistance and friction in the pivot are negligible, quantities that are conserved as the ball swings back and forth include which of the following? Two identical balls each of mass 0.1*10-3kg carry identical charges and are suspended by two non conducting threads of equal length. Two identical charged spheres suspended in air by strings of equal lengths makes angle 30 degree, which is same when they are suspended in liquid with density 0.8 g/cc. At apogee, a distance R1 from the planet, the satellite's angular speed is w. What is the angular speed of the satellite at perigee, a distance R2=R1/2 form the planet? Large Personalized Christmas Stockings, B) If gravitational effects from other objects are negligible, the speed of the rock at a very great distance from the planet will approach a value of The charges begin to leak from both the spheres at a constant rate. C It can be assumed to move in the Earth's gravitational field only. B) negative charges are transferred from the rod to the silk. A mass m is attached to the end of the spring and is released from rest at x=0. 9. Each string makes an angle theta with the vertical. 12.8 N is a unit vector that points from object 1 toward object 2.
