Q. The drawing shows an edge-on view of two planar surfaces that intersect and are mutually perpendicular. Surface 1 has an area of 2.2 m2, while surface 2 has an area of 3.5 m2. The electric field E in the drawing is uniform and has a magnitude of 250 N/C. It is directed towards the two perpendicular surfaces, making an angle 35o with the bottom surface. Find the electric flux through (a) surface 1 and (b) surface 2.
Two 12-cm-diameter charged rings face each other, 17.0 apart. Both rings are charged to + 40.0. What is the electric field strength at the midpoint between two rings.
A plane flies from base camp to Lake A, 300 km away in the direction 36.9° south of east. After dropping off supplies it flies to Lake B, which is 260km at 30.0° west of north from Lake A. find out the distance and direction from Lake B to the bas..
What is the weight of the displaced amount of water when the boulder is placed inside the tank (measured in N)? The tank had an original volume of water of 5000 L. while the boulder got placed inside the tank, the volume of water rose to 5010.165 ..
At one instant a bicyclist is 49m due east of a park's flagpole, going due south with a speed of 14 m/s. Then 40s later, the cyclist is 49m due north of the flagpole, going due east with a speed of 14m/s. For the cyclist in this 40s interval, what..
A 70.0 kg circus performer slides 4.90m down a pole to the circus floor, starting from rest. What is the kinetic energy of the performer as she reaches the floor if the frictional force on her from the pole (a) is negligible (she will be hurt) and (b..
Eight identical, non-interacting particles are placed in a cubical box of sides L = 0.2 nm. Find the lowest energy of the system (in electron volts) and list the quantum numbers of all occupied states if (a) particles are electrons and (b) particles..
A plastic ball in a liquid is acted upon by its weight and by a buoyant force. The weight of the ball is 4.8N. The buoyant force has a magnitude of 6.5N and acts vertically upward. External force acting on the ball maintains it in the state of res..
