18) What is the total charge on a lizard whose surface area is 4.6 cm2 and who has a surface charge density of 17.6 µC/m2. a. If the lizard was hovering in midair, what electric field strength would be needed to keep the lizard from falling to the ground if it weighed 3g.
19) A ball is held 5m above the ground. What is its potential energy? If it is dropped, how much kinetic energy does the ball have just before it hits the ground? What is its velocity at that same moment?
20) A dipole whose dipole moment is 6.0 nC•m sits in an electric field of 28 N/C. The field makes an angle of 61º to the central axis of the dipole. a. What is the potential energy of the dipole in the field? b. What is the torque on the dipole?

On planet Tehar, the acceleration of gravity is the same as that on Earth but there is also a strong downward electric field with the field being uniform close to the planet's surface. A 2.00 kg ball having a charge of 5.01 µC is thrown upward at a speed of 20.1 m/s and it hits the ground after an interval of 4.10 s. What is the potential difference between the starting point and the top point of the trajectory? kV

On planet Tehar, the free-fall acceleration is the same as that on Earth but there is also a strong downward electric field that is uniform close to the planet's surface. A 2.00 kg ball having a charge of 6.00 µC is thrown upward at a speed of 23.8 m/s and it hits the ground after an interval of 4.40 s. What is the potential difference between the starting point and the top point of the trajectory?
