1.	An electron of mass 0.90×10−30 kg under the action of a magnetic field moves in a circle of 2.0 cm radius at a speed of 3.0×106ms−1. If a proton of mass 1.8×10−27kg has to move in a circle of the same radius in the same magnetic field, then its speed will be ms−1.
Answer» An electron of mass $0.90 \times 10^{- 30} k g$ under the action of a magnetic field moves in a circle of 2.0 $c m$ radius at a speed of $3.0 \times 10^{6} m s^{- 1}$ . If a proton of mass $1.8 \times 10^{- 27} k g$ has to move in a circle of the same radius in the same magnetic field, then its speed will be $m s^{- 1}$ .

A parallel-plate capacitor having plate area A and plate separation d is joined to a battery of emf E and internal resistance R at t=0. Consider a plane surface of area A/2, parallel to the plates and situated symmetrically between them.

A horizontal curve with superelevation e = 0.05 (note, e=tanβ ) has a posted speed limit of 60 km/h. For this speed limit, only those vehicles with Y/X ratio(in figure) greater than 2 and travelling at speeds greater than 1.2 times the speed limit, will overturn. However, with recent increase in truck traffic the speed limit needs to be modified such that only those vehicles with Y/X ratio greater than 3 and travelling at more than 1.2 times the speed limit will overturn. What should be the new speed limit?(in km/hr round off to integer) (with respect to the figure, assume that the vehicle is travelling into the plane of the paper).50
