... Superposition principle: the presence of matter does not affect the electric field produced by a charged object. Intervening matter does not block the E field The resulting field is a superposition of two fields: Field of the other charge plus the field of induced dipoles. ...

... To complete a quarter-circle, the time taken is T/4. Since T is independent of v, the time taken is the same for the three objects. Note that if the objects have different masses and/or charges, we can use the above equation to rank the times: For example, doubling the mass m would require twice the ...

You’ll use these in the first part of the lab to look at magnetic field lines, the forces between permanent magnets, and torques on magnetic dipoles. In the second part of the lab you measure the magnetic ...

... 9. What is Newton’s Law of Gravitational attraction? GMm FG = 2 r 10. The sun collides with another star of the same mass and the as a result, the earth is blown to a distance from the sun that is twice as far as it was before. How does the force of gravity from the Earth on the Sun change? A) Does ...
