The potential at a point on the line will be,\rm E_{net}=\frac{5Kq}{r}.The net potential is the algebraic sum of the electric potential.

<h3>What is the electrical potential difference?</h3>

The amount of work performed in an electrical field to move a unit charge from one location to another is defined as the electrical potential difference.

In other terms, the potential difference is the difference in electric potential between two charged substances.

The traditional current flow is from positive to negative terminals, indicating the movement of positive charges in that direction.

\rm E_1 = \frac{Kq}{r} \\\\ E_2=\frac{K(4q)}{r}

The potential at a point on the line is found as;

\rm E_{net}=E_1+E_2 \\\\\ E_{net}=\frac{Kq}{r} +\frac{K(4q)}{r}  \\\\E_{net}=\frac{5Kq}{r}

Hence, the potential at a point on the line will be,\rm E_{net}=\frac{5Kq}{r}

At the local playground, a 21-kg child sits on the right end of a horizontal teeter-totter, 1.8 m from the pivot point. On the l
Alja [10]

Answer:

Counterclockwise

Explanation:

We need to calculate the clocwkise and the counterclockwise torque.

The clockwise torque is the one generated by the child sitting on the right. This torque is given by:

M_C = F d

where

F=mg=(21 kg)(9.8 m/s^2)=205.8 N is the force exerted by the child (his weight)

d = 1.8 m is the distance from the pivot point

So, the clockwise torque is

M_C = (205.8 N)(1.8 m)=370.4 Nm

The counterclockwise torque is the one generated by the adult pushing on the left, and it is given by

M_A = F d

where

F = 151 N is the force applied

d = 3.0 m is the distance from the pivot

Substituting,

M_A = (151 N)(3.0 m)=453 Nm

So, the net torque is

M_A - M_C = 453 Nm - 370.4 Nm=82.6 Nm

And since the counterclockwise momentum is greater than the clockwise one, the teeter-totter will rotate counterclockwise.

Suppose students experiment with the tube and a variety of darts. Some darts have higher masses than others but are the same aer
san4es73 [151]

Answer:

The dart with the small mass will travel the farthest distance.

Explanation:

Acceleration is proportional to force times mass, and inertia is proportional to mass. Inertia is the reluctance of a moving body to stop, and a stationary body to start moving (inertia increses with mass). Assuming they both have the same aerodynamic design, and that they are both launched with the same force applied for the same time duration, the dart with less small mass will accelerate faster than the big mass dart. From this we can see that the small dart will have covered a longer distance before the effect of the force stops, when compared to the more massive dart.
