Homework Statement
A point charge of -2.09*10^(-6) C is located in the center of a spherical cavity of radius 6.54 cm inside an insulating spherical charged solid. The charge density in the solid is 7.36×10^(-4) C/(m^3) .
Calculate the magnitude of the electric field inside the solid at a...
Homework Statement
The dipole moment of the water molecule is 6.17 x 10^-31 C*m . Consider a water molecule located at the origin whose dipole moment points in the +x-direction. A chlorine ion , of charge -1.60*10^-19, is located at x= 3.00*10^-3 m.
Assume that x is much larger than the...
So the magnitude of the total force equals F_ac + F_bc. If this is true, then masteringphysics should be accepting my answer of 2.83*10^-5, which it is not. I'm very frustrated at this point. I've only entered 8 possible answers with nothing correct. I know there has to be some silly little...
Ok so I've been trying to that exact thing. Since there is a repulsion between A and C, F_AC will be negative yes? And F_BC will be positive due to the attraction between B and C? Something has to be wrong with those assumptions on my part since I've checked the math repeatedly and F_AC +...
The problem I'm trying to solve involves the effect that two charges has on a third and I need to find the magnitude of the resulting force. In this particular problem it's the effect of A and B on C.
The work I've done so far is attached so please take a look. I've been trying to add...
