Answer:
a
The value at a point inside is Zero
b
The electric field is
Explanation:
We know from the problem that
The charge magnitude is
The radius of the spherical ball is
According to Gauss’s law, the enclosed charge within a conductor is zero which indicates that the electric field within the spherical ball is zero
On the outside, the electric field around the spherical ball is mathematically expressed as
Here a denotes a point outside the spherical ball with its value of
and k represents Coulomb's constant, valued at
=>
=>
To address this question, we will utilize concepts linked to centripetal force, aligning it with the static frictional force acting on the object. Using this relationship, we can derive the velocity and input the known values. The defined values are:
The maximum velocity can be determined using centripetal force,
Should be equal to,
As a result, the highest speed achievable through the arc without slipping is 9.93m/s
