Question

A dust speck with a mass of 5.00x10^-6

kg is initially traveling horizontally to the right

with a speed of 10.0 cm/s. The dust speck has 9.00x10^11

excess electrons on it and there

is an external magnetic field in that region of 1500 tesla directed out of the page. If the

dust speck is initially 2.0m above the ground, determine the time it will take it to strike

the ground. (Do NOT neglect gravity.)
