N = 120f/P.
where N=speed in rpm.
f = frequency.
P = Numbers of poles.
then calculate;
N=?, f = 800Hz, P = 4,
N=120 * 800/4.
= 24,000rpm
then 24,000 convert into rps because options are given in rps that's why we convert into rps.
i.e 24,000/60 = 400rps.

Given data:
F = 800 Hz p = 4 poles = 4/2 = 2 pair of poles.
Then Ns = 120*800/4 = 24000 rpm means that you can also use pair of pole using the following formula Ns = 60*800/2 = 24000 rpm you can convert rpm in rps like this 24000/60 = 400.
Thank you.

F = (PN)%120, where f in Hz, N in rpm.
Given f = 800Hz, P = 4.
By applying formula:
800Hz = (4*N)% 120.
=> N = 24000 rpm.
=> N = 24000% 60 = 400 rps.
Given f = 800Hz, P = 4.
By applying formula:
800Hz = (4*N)% 120.
=> N = 24000 rpm.
=> N = 24000% 60 = 400 rps.

N=?
Given data,
P=4.
f= 800Hz.
We know,
N= 120 f/P RPM.
=> N= 120*800/4.
=> N= 24000rpm.
=> N= 24000/60 rps.
Therefore N= 400rps.

1 RPS = 60 RPM.
And 1 RPM = 1/60 RPS or 0.1666 RPS.
The standard unit is RPM, but we have to convert it into RPS for this question.

All formula shown by our friends are clear as crystal. RPS means Revolutions Per Second.

N = 120f/p.
= 120*800/4 = 96000/4.
= 24000 rpm.
Then in RPS:
= 24000/60 = 400rps.
= 120*800/4 = 96000/4.
= 24000 rpm.
Then in RPS:
= 24000/60 = 400rps.

N = 120f/p.
= 120*800/4.
= 120*200.
= 24000 rpm.
= 24000/60 rps.
= 400.
= 120*800/4.
= 120*200.
= 24000 rpm.
= 24000/60 rps.
= 400.

N=RPM*pole/120
800=RPM*4/120
RPM=800*120/4
so RPM=24000
RPS=24000/60
RPS=400
800=RPM*4/120
RPM=800*120/4
so RPM=24000
RPS=24000/60
RPS=400
