a) 1.57 m/s
The sock spins once every 2.0 seconds, so its period is
T = 2.0 s
Therefore, the angular velocity of the sock is
The linear speed of the sock is given by
where
is the angular velocity
r = 0.50 m is the radius of the circular path of the sock
Substituting, we find:
B) Faster
In this case, the drum is twice as wide, so the new radius of the circular path of the sock is twice the previous one:
At the same time, the drum spins at the same frequency as before, therefore the angular frequency as not changed:
Therefore, the new linear speed would be:
And substituting,
So, we see that the linear speed has doubled.
Answer:
The charge on the dust particle is
Explanation:
From the question we are told that
The length is
The width is
The charge is
The mass suspended in mid-air is
Generally the electric field on the carpet is mathematically represented as
Where is the permittivity of free space with value
substituting values
Generally the electric force keeping the dust particle on the air equal to the force of gravity acting on the particles
