Complete Question
A 10-cm-long thin glass rod uniformly charged to 8.00 nC and a 10-cm
long thin plastic rod uniformly charged to -8.00 nC are placed side by
side, 4.20 cm apart. What are the electric field strengths E_1 to E_3 at
distances 1.0 cm, 2.0 cm, and 3.0 cm from the glass rod along the line
connecting the midpoints of the two rods
a.) Specify the electric field strength E1
b.) Specify the electric field strength E2
c.) Specify the electric field strength E3
Answer:
Explanation:
From the question we are told that
The length of the thin glass is
The charge on the glass rod is
The length of the plastic rod is
The charge on the plastic rod is
The distance between the materials is
The various distances to obtain electric field of are
The objective of the solution is to obtain the electric field at distance
from the glass rod along the line connecting its mid point
Generally electric field of a charge rod at a distance of r the line dividing the rod into half is mathematically represented as

Answer:
<em>P=33.6 \ W</em>
Explanation:
<u>Mechanical Work and Power</u>
Work is the amount of energy transferred by a force. It's a scalar quantity, with SI units of joules.
Being the force vector and
the displacement vector, the work is calculated as:
If both the force and displacement are parallel, then we can use the equivalent scalar formula:
Mechanical Power is the amount of energy transferred or converted per unit of time. The SI unit of power is the watt, equal to one joule per second.
The power can be calculated as:
Where W is the work and t is the time.
If an object of mass m has an acceleration a, the net force is:
F=m.a
The go-kart and rider have a mass of m=14 kg and accelerate at , thus the net force applied is:
The work done by the cart when traveling d= 40 m is:
Finally, the power for t= 100 seconds is:
P=33.6 \ W
