Answer:
Q = 29.4 x 10⁻⁹ C.
Explanation:
Electric field due to a charge Q at distance d is given by coulomb law as follows
Electric field
E = k Q /d²
where for air k which is a constant is 9 x 10⁹

Given E = 32.08 , d = 2.84 m
Putting these values in the relation above, we have
[/tex]
Q = 29.4 x 10⁻⁹ C.
Answer:
Explanation:
Given
Mass of solid uniform disk 
radius of disk 
mass of lump 
distance of lump from axis 
Moment of inertia is the distribution of mass from the axis of rotation
Initial moment of inertia of disk 

Final moment of inertia
=Moment of inertia of disk+moment of inertia of lump about axis




It might be 144.2 m but i’m not for sure:)
