1000/500 means that the voltage applied to the primary is 1000 Volt and so the secondary voltage is 500 Volt. If this is true, then the maximum current that you can deliver from the secondary is:

Vp = 1000.
Vs = 500.
(Apparent Power = V x I).
I = P/Vs.
I = 10 * 10^3 / 500,
I = 20 Amp.

As P apparent = Irms*Vrms.

As given value of we is Vmax. So must be divided by under root 2.

Do same for I because we need Imax?

Denominator on RHS will be 2 and this 2 will make 10 on LHS = 20A.
