Answer:
Work done = 4584.9 J
Explanation:
given: q1=3.0 mC = 3.0 × 10⁻³ C, r = 20 cm = 0.20 m, q1 = 34μC = 34 × 10⁻⁶ C
Solution:
Formula for the potential difference at the center of the circle
P.E = K × q1 q2 /r (Coulomb's constant k= 8.99 × 10⁹ N·m² / C²)
P.E = 8.99 × 10⁹ N·m² / C² × 3.0 × 10⁻³ C × 34 × 10⁻⁶ C / 0.20 m
P.E = 4584.9 J = Work done
<span>Under favorable conditions, including reaction time, a motor vehicle with good brakes going 50mph can be stopped within about 230 feet. </span>
Since a motor vehicle which is having good brakes, and the speed is not much high, so within 230 feet, It can be stopped including the reaction time.
A.
Kinematics is independent of mass, in most cases.
