solve it correctly please I will rate accordingly with multiple votes. Handwritten answer please.

an electron moves at 3.00 x 106 m/s perpendicular to the Earth's magnetic field at an altitude where the field strength is 8.00 x 10'6 T. What is the radius of the circular path the electron follows? m An electron moving at 2.00 x 105 m/s at a 45 degree angle through a 1.10 T magnetic field experiences what magnetic force? x 10'14 N A proton moving at 4.00 x 107 m/s experiences a magnetic force of 1.2 x 10'16 N. What is the strength of the magnetic field if there is a 30 degree angle between it and the proton's path? x 10'5 T
