When a charged particle moves at an angle of 19° with respect to a magnetic field, it experiences a magnetic force of magnitude F. At what angle (less than 90°) with respect to this field will this particle, moving at the same speed, experience a magnetic force of magnitude 1.8F?(adsbygoogle = window.adsbygoogle || []).push({});

can someone please tell me why doing a simple 19/f=x/1.8f cross-multiply and divide won't work????

it's my last problem on this dang homework!:grumpy:
