25. if u consider the highest point as a circular arc, then the only force acting on the particle is the downward force mg.

mg=mv^2/r

=> r=v^2/g.........(1)

but, vel of particle at highest point is ucos@

putting this in (1)

r=(ucos@)^2/g

Men have been taught that it is a virtue to agree with others. But the creator is the man who disagrees. Men have been taught that it is a virtue to swim with the current. But the creator is the man who goes against the current. Men have been taught that it is a virtue to stand together. But the creator is the man who stands alone.
