Consider a thin slice of the first rod, of thickness dx1, that is located a distance x1 from the origin and a thin slice of the second rod, of thickness dx2, that is located a distance x2 from the origin. Enter an expression for the magnitude of the force dF12 that the thin slice of rod 1 exerts on the thin slice of rod 2, in terms of L1, L2, Q1, Q2, x1, x2, and the Coulomb constant k.

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

this would be about 43%
