A hypothetical charge 42pC with mass 66fg has a speed of 59km/s and is ejected southward entering a uniform magnetic field of unknown magnitude and direction. If the path traced is clockwise, 1. Find the magnitude and direction of the magnetic field that will cause the charge to follow a semicircular path (given the diameter 29m). 2. Find the time required for the charge to complete a semi-circular path from point K to point L.

Question
A hypothetical charge 42pC with mass 66fg has a
speed of 59km/s and is ejected southward
entering a uniform magnetic field of unknown
magnitude and direction. If the path traced is
clockwise,
1. Find the magnitude and direction of the
magnetic field that will cause the charge to
follow a semicircular path (given the
diameter 29m).
2. Find the time required for the charge to
complete a semi-circular path from point K
to point L.
3. Find the magnitude and the direction of
the magnetic force at point L.
