(a)
To determine:
The reason for bending in the path of the charged particle.
(a)

Answer to Problem 1E
Solution:
The bending of path of the charged particles is because of presence of charge on the plates.
Explanation of Solution
When a charge particle comes in vicinity of another charge it gets either attracted or repelled by the charge. Same charges repel each other and opposite charges attract teach other.
The path of the charged particle bends because when it passes between two electrically charged plates it interacts with the charges on the plate and experiences a force.
The presence of charged plates bends the path of the charged particle.
(b)
To determine:
The sign of electrical charge on the particle.
(b)

Answer to Problem 1E
Solution:
The sign of electrical charge on the particle is negative.
Explanation of Solution
A positive charge gets attracted by a negative charge and vice versa. The particle is bending towards the positively charged plate it means it is getting attracted by the positive charge. So, the charge on the particle must be opposite that is it is negatively charged.
The particle is getting attracted by positively charged plate. So, the charge on it is negative.
(c)
To determine:
The change in bending on increasing the charge on the plate.
(c)

Answer to Problem 1E
Solution:
As the charge on the plates is increased, the bending also increases.
Explanation of Solution
The extent of attraction or repulsion increases on increasing the charge. As the charge on plates is increased the attraction felt by charged particle will increase and hence the bending is also expected to increase.
Increase of charge on plates, increases the bending.
(d)
To determine:
The change in bending on increasing the mass of the particle.
(d)

Answer to Problem 1E
Solution:
As the mass of the particle is increased, the bending decreases.
Explanation of Solution
The extent of attraction or repulsion is inversely proportional to the mass of the particle. As the mass of the particle is increased the attraction felt by charged particle will decrease and hence the bending is also expected to decrease.
Increase of charge on plates, decreases the bending.
