A particle enters a uniform magnetic field initially traveling perpendicular to the field lines and is bent with a circular arc of radius R. If this particle was traveling two times as fast, the radius of its circular arc would be? EXPLAIN

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft

365.25 earth days are in the year of a light year

a. spokes of a wheel.

as indicated in the question radial contains rad, also found in radius, so the fracture's would span the radius.
