Two point charges are fixed on the y axis: a negative point charge q1 = -24 µc at y1 = +0.19 m and a positive point charge q2 at y2 = +0.33 m. a third point charge q = +8.0 µc is fixed at the origin. the net electrostatic force exerted on the charge q by the other two charges has a magnitude of 18 n and points in the +y direction. determine the magnitude of q2.

4.51 * 10^{-5} C

Explanation:

The force between two charge  q and q1 is given as

= 47.86 N in the +y direction

We need the force between q and q2 to be (47.86 - 18) =  29.86 N in the other direction to get the desired result.

solving for q2,

which piece of furniture will have the most inertia and give the furniture movers the most difficulty in moving?  

answer

a 75kg dining table

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.
