Q. A dog pulls on a pillow with a force of 2.2 N at an angle of 40° above the horizontal. Find the x and y components of the force.
Q. Two particles are fixed to an x axis: particle 1 of charge q1 = +1.9 multiplied by 10-8 C at x = 20 cm and particle 2 of charge q2 = -3.00q1 at x = 70 cm. At what coordinate on the axis is the net electric field produced by the particles equal to zero?
