A hypothetical planet has a radius of 500km and acceleration due to gravity of 3.0m/s². What is the gravitational acceleration 100km above it's surface? What is the mass of the planet

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

the independent variable, or the one that is intentionally manipulated is the speed.

answer; how far out of place which the object finished relative to the starting location;
