A pilot ( with a mass of m ) in an aircraft follows a vertical circular motion of radius 2.70 km at a constant speed of 225 m/s. If the normal force acting on the pilot at the bottom of the circle is 2082 N, calculate m.

Which diagram correctly demonstrates the various forces acting on a ball moving horizontally with some speed?

The electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e
