Q1:

The maximum radial distance of a Lemniscate curve, having maximum polar angle a, is

A 3 R sin α

B 3 R sin2α

C 3 R sin 2α

D 3 R sin α/2

E none of these.

ANS:A - 3 R sin α

The equation of Lemniscate curve is given by r = p/3sin2α. where 'P' is the polar ray of any point, 'r' is the radius of curvature at that point and 'α' is the polar deflection angle.
