The electric charge on surface is 2.66×10-⁹NC
<h3>What is an electric charge?</h3>
The electric charge is the property of subatomic particle that causes it to experience a force when placed in an electric and magnetic field.
We have given ,
Electric field= 1.5×10⁴N/C
Radius = 4cm = 0.04m
E = k× q/ r²
1.5×10⁴×16×10-⁴/9×10⁹=q
q= 2.66×10-⁹C

Answer:
Explanation:
The time taken to complete one revolution is the period and is defined as:
The angular speed is given by:
Replacing (2) in (1) and solving for :
Answer: A, a polished pale yellow surface would likely be the best reflector of heat energy.
Net work = Work done - Amount Work release
W = 106 - 74 = 32 J
In short, Your Answer would be: Either C or D
Hope this helps!
