The gravitational field g due to a point mass M may be obtained by analogy with the electric field by writing an expression for the gravitational force on a test mass, and dividing by the magnitude of the test mass, m. Show that Gauss' law for the gravitational field reads:
phi = oint...
Wouldn't you just add the absolute value of both electric fields since the electric fields from both of the plates are headed towards the same direction?
Two infinite-plane non-conducting, thin sheets of uniform surface charge p1 = 12.30 uC/m2 and p2 = -3.30 uC/m2) are parallel to each other and d = 0.615 m apart. What is the electric field between the sheets? (Note: the field is positive if it is parallel to the vector x).
Hi, I've tried this...
Hello, in an electric field, are the magnitudes of the field the same regardless of the spatial location? Or is the field's magnitude similar to the force experienced by the test charge where it gets smaller as you move away from the source charge? Any clarification would be appreciated.
Hello, can someone explain to me what is the difference between center mass acceleration and angular acceleration? If i have an uniform disk laying still, then i give it a force to make it spin while it stays put. The angular acceleration obviously has a number. What about the acceleration of...
