Explanation:
Answer:
Angular speed = 2.5 rev/sec
Explanation:
εo= 80 V
wo = 1600 rev/min
ε = 7 V
εo=BANwo..........(1)
ε=BANw..............(2)
Dividing equation (1) by (2) we get,
εo/ε =wo/w
Or, w=εwo/εo
By putting values we get,
w= 1600×7.5/80
w = 150 rev/min
Or, w= 2.5 rev/sec
So,
Angular speed = 2.5 rev/sec.
