The people on this forum where so helpful with my last problems that I'm posting again! Here are the two I'm having trouble with:(adsbygoogle = window.adsbygoogle || []).push({});

1) What must be the charge (sign and magnitude) of a 1 g particle for it to remain stationary when placed in a downward-directed electric field of magnitude 530N/C? I know the equation E=F/q, but I'm not sure how to apply it in this case.

2) Why is use of the earth's magnetic field not a feasible means of flight?

Thanks again :)
