Three particles are arranged in the `xy` plane, each a distance of  0.510 m from the origin. Particle 1 with a mass 42.9 kg is located on the +y-axis. Particle 2 with a mass of 34.0 kg is located in the direction 32.9° below the +x-axis. Particle 3 with a mass of 49.1 kg is located in the direction 15.1° to the left of the `-`y-axis.

a) What is the x-component of the contribution to the gravitational field at the origin from particle 1?

b) What is the y-component of the contribution to the gravitational field at the origin from particle 1?
