Question

Hiya,

Dt/dr =k/r^2

Is this directly solvable or do I need to separate variables.

I've got t=-k/r+c from the former and something along the lines of r^3=kt+c from the latter.

Think I'm doing it all wrong.
Thanks

dt/dr = k/r^2

dt = k dr/r^2

try t = k (-1/r) + c

I do not know where you got the other.
