    Answer:

    The magnitude of the magnetic field is 10.19 T.

    Explanation:

    Given that,

    Charge on the doubly charged molecule, q = 2e

    Magnetic force, F=6.75\times 10^{-16}\ N

    Speed of molecule, v = 207 m/s

    The angle to the direction of the field is 74.9 degrees.

    We need to find the magnitude of magnetic field. The formula of magnetic force is given by :

    F=qvB

    B is magnetic field

    B=\dfrac{F}{qv}\\\\B=\dfrac{6.75\times 10^{-16}}{2\times 1.6\times 10^{-19}\times 207}\\\\B=10.19\ T

    So, the magnitude of the magnetic field is 10.19 T.
