Auniform line charge λ is placed on an infinite straight wire, a distance d above a grounded conducting plane. (let’s say the wire runs parallel to the x-axis and directly above it, and the conducting plane is the x y plane.) (a) find the potential in the region above the plane. [hint: refer to prob. 2.52.] (b) find the charge density σ induced on the conducting pla

Mass (kg) force (n) 5 25 10 50 15 75 20 100 a student was trying to find the relationship between mass and force. he placed four different masses on a table and pulled them using a spring scale. the table shows the different masses used in the experiment and the force required to pull each mass. the student concluded that more force was required to pull heavier objects. what comment would you make regarding his conclusion? a) no clear relation can be observed between mass and force from the data. b) there is a direct proportion between the mass and force listed in the table. c) gravity should have been taken into account while performing the experiment. d) there is an inverse proportion between the mass and force listed in the table.
