Answer:

933.804423995 m/s²

Explanation:

q_1 = Charge on particle 1 = 67 µC

q_2 = Charge on particle 2 = -25 µC

r = Distance between the particles = 47 cm

k = Coulomb constant = 8.99\times 10^{9}\ Nm^2/C^2

m = Mass of particle = 73 g

Electric force is given by

F=\dfrac{kq_1q_2}{r^2}\\\Rightarrow F=\dfrac{8.99\times 10^{9}\times -25\times 10^{-6}\times 67\times 10^{-6}}{0.47^2}\\\Rightarrow F=-68.1677229516\ N

The magnitude of force is 68.1677229516 N

Acceleration is given by

a=\dfrac{F}{m}\\\Rightarrow a=\dfrac{68.1677229516}{0.073}\\\Rightarrow a=933.804423995\ m/s^2

The acceleration is 933.804423995 m/s²

what are the common elements that make up series and parallel circuits , and how are circuits diagrammed?​
Ahat [919]
<h2>Answer:</h2>

A series circuit occurs when the elements are connected along a simple path so the same current flows through all the elements. On the other hand, a parallel circuit occurs when there are two or more paths for the electricity to flow. The diagram are shown in the Figure below. We have chosen a source and resistors to illustrate this problem.
