Four Point Charges Are Placed At Different Positions On The Circumference Of A Circle As Shown In The Figure The Area 1 (50.95 KiB) Viewed 13 times

Four point charges are placed at different positions on the circumference of a circle, as shown in the figure. The area of the circle is 20 mm². The charges are: q₁ q2 = 93 = 94 = +9.0 µC and 0 = 30°. Vier puntladings word op verskillende posisies op die omtrek van 'n sirkel geplaas, soos in die figuur aangedui. Die oppervlakte van die sirkel is 20 mm². Die ladings is: q1 = 92 93 94 = +9.0 μC en 0 = 30° (a) 92 9₁ 93 Calculate the net electric field (magnitude and direction) at the centre of the circle. Bereken die netto elektriese veld (grootte en rigting) by die middelpunt van die sirkel.
