Here is a picture of my work. It's easier than typing it out!
Answer:
Angular acceleration,
Explanation:
It is given that,
Displacement of the rotating wheel,
Time taken, t = 2.9 s
Initial speed of the wheel,
Final speed of the wheel,
Let is the angular acceleration of the wheel. Using the third equation of kinematics to find it as :
So, the angular acceleration of the wheel is . Hence, this is the required solution.
What assignment, you have to work with me here i don't know what were working on
We have that the electric field at the center of the metal ball due only to the charges on the surface of the metal ball is
From the question we are told that
A solid metal ball of radius 1.5 cm
bearing a charge of -15 nC is located near a hollow plastic ball of radius 1.9 cm bearing
uniformly distributed charge of -7 nC
The distance between the centers of the balls is 9 cm
Generally the equation for the electric field is mathematically given as
