Two very long line charges are set up along lines that areparallel to the z-axis, so they set up Electric fields strictly in the xy plane. One goes throughthe x-axis at x = −0.40 m and has charge a density λ1 = +12.0 μC/m, the other goesthrough the x-axis at x = +0.40 m has charge density λ2 = −8.0 μC/m.A. Find the Electric field at point A: (0.40, 0.80) (distances in meters). Give answersin unit vector notation and draw a graph of the x-y plane with the E-fields you justfound.B. Find a point on the x-axis at which the total E-field is 0.
In order to increase the amount of exercise in her daily routine, Tara decides to walk up the four flights of stairs to her car instead of taking the elevator. Each of the steps she takes are 18.0 cm high, and there are 12 steps per flight.
(a) If Tara has a mass of 77.0 kg, what is the change in the gravitational potential energy of the Tara-Earth system (in J) when she reaches her car?
]
(b) If the human body burns 1.5 Calories (6.28 x 10³ J) for each ten steps climbed, how much energy (in J) has Tara burned during her climb?
]
(c) How does the energy she burned compare to the change in the gravitational potential energy of the system?
