To solve this problem we will apply the concepts given from the circular movement of the bodies for which we have that the centripetal Force is defined as a product between the mass and the velocity squared at the rate of rotation, mathematically this is
Where,
m = Mass
v = Velocity
r = Radius
Our values are given as
Rearranging to find the velocity we have that,
Therefore the maximum speed can the mass have if the string is not to break is 29m/s
Answer:
a
b
c
Explanation:
From the question we are told that
The magnitude of electric dipole moment is
The electric field is
The distance between the positive and negative charge center is mathematically evaluated as
Where e is the charge on one electron which has a constant value of
Substituting values
The maximum torque is mathematically represented as
Here
This because at maximum the molecule is perpendicular to the field
substituting values
The workdone is mathematically represented as
where is the potential energy at 180° which is mathematically evaluated as
Where the negative signifies that it is acting against the field
substituting values
and
is the potential energy at 0° which is mathematically evaluated as
substituting values
So
