The charges and coordinates of two charged particles held xed in an xy plane are q1 = 2.58 uC,x1 = 5.80 cm, y1 = 0.391 cm and Q2 = 4.62 uC,x2 = -1.54 cm, Y2 = 1.24 cm. Find the (a) magnitude and {b} direction {with respect to +x-axis in the range (-180;180]] of the electrostatic force on particle 2 due to particle 1. At what {c}x and (d) ycoordinates should a third particle of charge G3 = 5.99 pC be placed such that the net electrostatic force on particle 2 due to particles 1 and 3 is zero? {a} Number n Units v {b} Number n Units v {c} Number n Units V {d} Number n Units V Two particles are fixed to an x axis: particle 1 of charge q1 = 1.61 x 10-8 Cat x = 27.0 cm and particle 2 of charge q2 = -4.00q1 at x = 78.0 cm. At what coordinate on the x axis is the electric field produced by the particles equal to zero? Number i UnitsA certain brand of hotdog cooker works by applying a potential difference of 125 V across opposite ends of a hot dog and allowing it to cook by means of the thermal energy produced. The current is 11.4 A, and the energy required to cook one hot dog is 6 1.9 kJ. If the rate at which energy is supplied is unchanged. how long will it take to cook three hot dogs simultaneously?
