PHYS208 Fundamentals of Physics II
Answer for Ch. 23, 3E
to the right.
Answer for Ch. 23, 17P
Answer for Ch. 23, 22P
E = 2 sqrt(2) k q / a2
direction is up.
numerical value: 1.02 x 105 N/C
Answer for Ch. 23, 52P
The final speed is 2.7 x 10-6 m/s.
The electric field has magnitude 1.0 x 103 N/C.
Answer for Ch. 23, 57P
The acceleration of the electron in the electric field is
3.5 x 1014 m/s2, downward.
With that information this becomes a kinematics calculation, similar to a trajectory near the surface of the earth;
the electron hits the upper plate 2.73 cm from the edge.
