A point charge of 7nC is at a fixed location of (4mm, 3mm, 0). Another point charge of -5nC is located at a fixed position of (3mm, 4mm, 0). What will be the force acting on an electron placed in the origin of the coordinate system

Find v(t), given acceleration a(t)=7j and initial velocity v(0)=k

If y gets smaller as x gets bigger and y have an relationship?

Identify the correct relation showing that the radius r of the orbit of a moon of a given planet can be determined from the radius r of the planet, the acceleration of gravity at the surface of the planet, and the time τ required by the moon to complete one full revolution about the planet. determine the acceleration of gravity at the surface of the planet jupiter knowing that r = 71 492 km and that t= 3.551 days and r= 670.9 × 10^3 km for its moon europa.
