For radial flow,

a = V^2/r.
Here, V = 1/r^2 hence,
a = [(1/r^2)^2]/r,
= (1/r^4)/r,
a = 1/r^5.

Thanks @Aparna.

For radial flow : a =v2/r.

V=k/r2, hence put the value in above equation, then a = k2/r5.

a = V2/r = (1/r2)2/r = 1/r5.

What condition to apply r/2 in V in the question?

Please anyone tell me.
