What is the magnitude of the magnetic force (in N) on a charged particle (Q= 3 mC) moving with a speed of 72 km/s in the positive x direction at a point where
Bx = 5.0 T, By = -4.0 T, and Bz= 3.0 T?

technology is the application of the knowledge gained by science.

this would be about 43%

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
