A large charge distribution Q exists at the center of a cube. It is surrounded by six smaller charges, q , each facing a direction perpendicular to a face of the cube.What is the electric flux through one of the sides of the cube?

A meteor is approaching. Assume that the meteor started very far away from the earth and just grazes the earth. You may ignore all other forces except gravitational force between earth and meteor. Assume that mass of the meteor is much smaller than mass o...

A physical pendulum consists of a body of mass contained in the xy-plane. The moment of inertia of the object about an axis perpendicular to the plane and passing through the object's center of mass is I_cm . The object oscillates in the xy-plane about th...

The angular momentum of a planet is conserved if taken with respect to: a)The center of the ellipse b) The focus of the ellipse at the sun c)The focus of the ellipse opposite the sun d)Both foci of the ellipse

After the velocity selector, a mass spectrometer allows the charged particle to enter a region of magnetic field only, where it follows a curved trajectory and hits a detector which records his position. Your mass spectrometer has the velocity selector se...

block 3M slides downward without friction. The string connecting blocks 3M and M is ideal (that is, its mass can be neglected and it is not stretchable). The pulley, a uniform solid disc of mass M and radius r , rotates without slipping. Find the accelera...

doesnot be theta= 81.7872degree? I have R=12m

Hi, Damon you mean c is the answer?

Thank you

Thank you very much Damon

Thank you very very much

Hi enjoy,I got (2*g/5)(3*sin(theta-1) which is not in options.. Can you please show me how to get 2*g/9? I appreciate your help.

In question no.2 a) torque would be 2*F*r/2? I am confused that from top view, which force we have to use?
