Three positive particles of equal charge +11.o micro C, are located at the corners of an equilateral triangle of sides 15.0cm. Calculate magnitude and direction of the net force on each particle.
DUUUUUUUUUH!
THIS IS SO EASY!
LOOK IN YOUR BOK, IDIOTIC DUDE! R U A BOY AND HOT, HOTTIE SEEYA L8ER
thanks for your help ellie!
Yikes!
Sorry about the crazy response! It sure doesn't look like physics to me!
If you put each of the charges at the corners of equilateral triangles, then the angles are 60. Then, for each charge, you need to calculate the net electrical field that that charge feels. The sides are length r.
For example, consider triangle with q1 at lower left, q2 at top, and q3 at lower right.
the field felt by q1:
E net (x direction) = E2 (x direction) + E3 (x direction.
E net x = E2 cos60 + E3
= k/r^2 * q2cos60 + k/r^2 * q3
E net y = E2 (y direction + E3 (y direction)
E net y = E2 sin60 + 0
k/r^2 * q2sin60
Now you have the electrical field felt by q1.
To get the force, use F = qE
Hope this is a start for you!!
