Answer:
1.been both -ve charged or both +be charged particles
2. 3.52mC
Explanation:
For the charge particle to cause an extension or movement of the string from its unrestrained position they would have been both -ve charged or both +be charged particles that's because like charges repel.
Now the Force sustain by the extended string is
F = Ke;
Where K is the force constant of the string, 320 N/m
e is the extension,0.033 m
F = 320 × 0.033 =10.56N
2.But according to columns law of charge;
F = kQ1 Q2
But Q1=Q2{ since the charge are of the same magnitude}.
Hence F = KQ^2
Where K is columns constant =9×10^9F/m
Hence Q=√F/K
Q= √10.56/9×10^9
=3.52×10^-3C
= 3.52mC
If Aldebaran were to explode tonight then we will be able to see this explosion on the Earth in approximately 65 years. A light-year is a distance that light travels in one (1) year.
<h3>What is a light-year?</h3>
A light-year can be defined as a unit equal to the distance that light needs to travels in one (1) year on the Earth.
One light-year can be considered as a unit that equates to approx. 9.7 trillion kilometers (km) or 5.9 trillion miles.
In consequence, a light-year is a distance unit instead of a unit of time, and this unit was developed by Otto Ule.
