First compute the force.
F = m a,
in Newtons
Then use F = e V B sin 25 to get the field strength B, in Tesla.
You will need to use the mass, m, and the charge, e, of the electron. These are readily available.
HI!
Can you guide to which equation to use for this problem:
An electron with the speed of 2 x 10^7 m/s enters a magnetic field with a velocity vector 25^0 away from the magnetic field direction. If it experiences an acceleration of 1.5 x 10^16 m/s^2, determine (absolute value) B.
