<u>Answer</u>
1.26 rad/s
the first step is to find the frequency of the wheel.
The wheel rotates at rate of 5 revolutions in 25 seconds. The frequency is the number of revolutions per second.
frequency (f) = 5/25
= 1/5
= 0.2 Hz
Angular velocity = 2πf
= 2×π×0.2
= 0.4π rad/s or
= 1.26 rad/s
Answer:
V = 360 kV
Explanation:
Given that,
Charge, q = -2µC
We need to find the electric potential difference of 5cm from a point charge.
We know that the formula for the electric potential is given by :
or
So, the electric potential difference is 360 kV.
