Suppose an electron is trapped within a small region and the uncertainty in its position is 35.0x 10-15 m. What is the minimum uncertainty in the electron's momentum? Number i UnitsWhen light with a wavelength of 268 nm is incident on a certain metal surface, electrons are ejected with a maximum kinetic energy of 3.29 x 10-1" J. Determine the wavelength (in nm) of light that should be used to double the maximum kinetic energy of the electrons ejected from this surface. Number UnitsA tiny ball (mass = 0.014 kg) carries a charge of -14 //C. What is the electric field magnitude that would cause the ball to float above the ground? Number Units VA vertical wall (5.8 m x 2.9 m) in a house faces due east. A uniform electric field has a magnitude of 150 N/C. This field is parallel to the ground and points 480 north of east. What is the electric flux through the wall? Number i Units V
