1.	A line charge λ perunit length is lodged uniformly onto the rim of a wheel of mass Mand radius R. The wheel has light non-conducting spokesand is free to rotate without friction about its axis (Fig. 6.22). Auniform magnetic field extends over a circular region within the rim.It is given by,B = − B0 k (r ≤ a;a < R)= 0 (otherwise)What is the angularvelocity of the wheel after the field is suddenly switched off?
Answer» A line charge λ per unit length is lodged uniformly onto the rim of a wheel of mass M and radius R. The wheel has light non-conducting spokes and is free to rotate without friction about its axis (Fig. 6.22). A uniform magnetic field extends over a circular region within the rim. It is given by, B = − B₀ k (r ≤ a; a < R) = 0 (otherwise) What is the angular velocity of the wheel after the field is suddenly switched off?

A line charge λ per
unit length is lodged uniformly onto the rim of a wheel of mass M
and radius R. The wheel has light non-conducting spokes
and is free to rotate without friction about its axis (Fig. 6.22). A
uniform magnetic field extends over a circular region within the rim.
It is given by,

B = − B₀ k (r ≤ a;
a < R)

= 0 (otherwise)

What is the angular
velocity of the wheel after the field is suddenly switched off?

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
