Fundamentals: N06P3Q5

eii) the acceleration is perpendicular to velocity hence parabolic motion.
iii) the force is in opposite direction , hence the curve is in opposite direction.

fi)1. In a vacuum , no tracks can be observed . To observe tracks there must be ionisation and condensation of vapour
2. If beta can emerged from the plates as shown in the fig. 5.1 , alpha particle would have a small radius of curvature(will not be as shown in diagram) . This is due to the charge mass ratio.

fii) The source of radiation have the same energy. If alpha and beta have the same energy they would have different speed due to their masses.
