Question
Please explain and show any work (5) [6 points] A particle with mass m 1.8 × 10-15 kg and magnitude of charge Igl = 6.0 x 10-6 C is projected into the uniform field between two parallel plates (4.0 cm long and separated by 2.0 cm) hooked up to a battery as shown in the figure. It takes the particle = 2.0× 10-8 s to travel the distance between the plates and as it exits, it just barely clears the far plate. The electric field is zero excent in the space between the neo plates. The particle enters the fie 4 em (a) 13 points) What is the sign of the charge? How can you tell? (b) [3 points] If the plates remain connected to the battery and the top plate is moved up, such that the distance between the plates is increased, while the bottom plate is held in place. Everything else is the same in the problem. Which of the trajectories below is most correct? Explain your reasoning.Explanation / Answer
a)
as the charge moves towards the negative plate.
as the electric field between the plates is upwards.
as the charge moves in the direction of electric field ,
the charge must be POSITIVE
b)
here , when the top plate is moved ,
electric field , E = potential difference/d
the electric field will decrease ,
which result in the lower deflection of the charge .
Now, for the lower deflection , the correct option is last one
