a cyclotron is a device which is used to accelerate charged particles to higher energies.
PRINCIPLE: when a charge q moves normal to a magentic field it experiences magnetic lorentz force due to which it moves in circular path .
when a charged particle of mass ' m' and charge q is accelerated towards the Dee having -ve polarity at that instant and normal magnetic field produces magnetic lorentz force which provides centripetal force for the electron to move in a circular path of radius 'r' .By the time the particle reaches the gap the polarity changes thus the particle is again accelerated towards the Dee having -ve polarity at that instant. thus the particle moves in spiral path increasing the radius and velocity.we it reaches the edge the particle is taken out with the help of a deflector plate

. Because of the rotation of the earth, a plumb bob may not hang exactly along the direction of
the earth’s gravitational pull (its weight) but deviates slightly from this direction. Calculate the
deviation (a) at 40 latitude, (b) at the poles, and (c) at the equator

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
