Oscillations in a uniform magnetic field

In the region are shown two identical non conducting fixed wedges separated by a certain distance.There exist a magnetic field everywhere (shown in the figure is only some part)of magnitude 1 Tesla A small particle of some charge and mass is released from some point on the wedge at t=0 such that it undergoes oscillations in between the wedges such that its time period is minimum of its type. The particle just grazes(does not touch) over the ground at (t=T/5)sec where T is the time period of oscillations. In a separate experiment if the particle undergoes uniform circular motion about a point then the angular momentum observed about that point is 1/5 times the magnetic moment due to the charge in SI units. The maximum height of 1/5 m above ground is reached (which is higher than)the initial position during the subsequent motion. Take $g=10m/s^2$ .The acute angle in degrees the wedge makes with the horizontal is? The oscillations are symmetric about a certain axis Round your answer to the nearest integer. Note that initial position can be found with the given information
