Write the electric field at point P in component form. Assume that xx-axis is horizontal and points to the right, and yy-axis points upward. Express your answer in terms of the variables Q, L, unit vectors i^, j^ and appropriate constants.

Asled is being held at rest on a slope that makes an angle θ with the horizontal. after the sled is released, it slidesa distance d1 down the slope and then covers the distance d2 alongthe horizontal terrain before stopping. find the coefficient ofkinetic friction μk between the sled and the ground, assumingthat it is constant throughout the trip. find the coefficient of kinetic frictionμk. express your answer in terms of someor all of the variables d1, d2, and θ.
