1rpm=60rps.
so 1rps 1/60 rpm and,
400rps=400 * 1/60 rps.
I think the answer is wrong @Kiran.

400rps=400 * 1/60 rps.

rps=400*60=24000=Ns.
P = 2
Ns = 120f/p.
120*f/Ns*p.
f = Ns*p/120,
f = 24000*2/120,
f = 400.
P = 2
Ns = 120f/p.
120*f/Ns*p.
f = Ns*p/120,
f = 24000*2/120,
f = 400.

As per the definition, frequency means that the number of cycles completed by one rotation.

If this is a single phase generator , how are we considering the angle to be 120 degrees?

rps=400*60=24000=Ns.
P=2
Ns=120f/p
120*f/Ns*p
f=Ns*p/120
f=24000*2/120
f=400.
P=2
Ns=120f/p
120*f/Ns*p
f=Ns*p/120
f=24000*2/120
f=400.

For rpm; Simply convert this to the minute, we multiply 60 with rps 400*60.

n(rps) = 400 rps.
p(pole) = 2.
f = (pn/2).
f = (2*400/2) => 400Hz.
p(pole) = 2.
f = (pn/2).
f = (2*400/2) => 400Hz.

@Hassan.
Formula contains Ns syncronous speed ,Ns = (( 120 * f ) /p).

F = PN/120
= 400*60*2/120
= 400Hz Because 400*60 rps= 400 rpm.
= 400*60*2/120
= 400Hz Because 400*60 rps= 400 rpm.

N=120F/P
N=400rps=400*60rpm
p=2
F=NP/120
=400*60*2/120
=400HZ
N=400rps=400*60rpm
p=2
F=NP/120
=400*60*2/120
=400HZ
