1-The Electrons in a beam are moving at 2.7×108 m/s in an electric field of 15000 N/C. What value must the magnetic field have if the electrons pass through the crossed fields undeflected?
Answer in units of μT.

2- (part 1)

A 0.207 kg mass is attached to a spring with a spring constant 163 N/m so that the mass is allowed to move on a horizontal frictionless surface. The mass is released from rest when the spring is compressed 0.134 m. Find the maximum force on the mass. Answer in units of N.

(part 2)

Find the maximum acceleration. Answer in units of m/s2.

    A scanning electron microscope uses a uniform 15.0-kN/C electric field to accelerate electrons horizontally toward the subject to be imaged. After travelling 5.0 cm the electrons are accelerated to a speed of 1.62x107 m/s. The next step is to deflect the electrons so that they can scan across the sample—hence the scanning electron microscope. To accomplish this, the electrons are directed between a pair of oppositely charged parallel plates, which produce a uniform electric field of 6.42x103 N/C perpendicular to...
