Question

A particle is projected horizontally from the top of a cliff of
height H with a speed √ (2gH) The radius of curvature of the
trajectory at the instant of projection will be
a) H/2
b) H
c) 2H
d) infinity

Neha Gupta · Accepted Answer

Radius of curvature of the particle at the time of projection is
equal to height of that point i e H
