An object is projected from a height of 80 m above the ground with a velocity of 40ms-1 at an angle of 30° to the horizontal. The time of flight [ g ≈ 10m/s\(^2\)
A proton moving with a speed of 1.0 x 10\(^6\)ms\(^{-1}\) through a magnetic field of 1.0T experiences a magnetic force of magnitude 8.0 x 10\(^{-14}\) N. The angle between the proton's velocity and the field is
[1.6 x 10\(^{-19}\)C]
