A forestry worker accidentally strikes a pipe with the end of a
pickaxe while trying to dig a hole. If
the pickaxe strikes with a force of
2000 N and the end of the pickaxe
measures 0.02 m by 0.01 m, how much
pressure is exerted on the pipe by the
pickaxe?

3. a particle with initial velocity v⃗ 0=(5.85×103m/s)j^ enters a region of uniform electric and magnetic fields. the magnetic field in the region is b⃗ =−(1.35t)k^. you can ignore the weight of the particle. a. calculate the magnitude of the electric field in the region if the particle is to pass through undeflected, for a particle of charge +0.640 nc.
