Acharge q with mass m has a velocity far away. a small metallic loop of area a and resistance r is fixed and oriented such, that it and the vector 7 are in the same plane. the impact parameter of the charge with respect to the loop is h. assuming that r, there is not gravity and air resistance, find the velocity (magnitude and direction) of the charge after a very long time

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.
