When an object moves its length contracts in the direction of motion. The faster it moves the shorter it gets in the direction of motion.
The object in this question moves and then stops moving. So it's length first contracts and then expands to its original length when the motion stops.
The speed doesn't have to be anywhere near the speed of light. When the object moves its length contracts no matter how fast or slow it's moving.
The sign of the charged particle is positively charged.
<h3>What is potential difference?</h3>
- When a single charge is transported in an electric field, work is done by the potential difference (also known as electrical potential).
- There is potential energy stored in this charge that could flow when work is done on it.
- Voltage is the possibility of a single charge flowing. The need to flow increases with voltage.
- Here, voltage can be the potential differences.
The potential difference between the 2 points determines the movement of that particle. An electron moves from lower to higher potential which is negatively charged, and a positively charged particle moves from higher to lower potential.
Now, since the particle is moving from a point A having 160 v potential to point B having 100 v potential that is it is moving from higher potential to a lower potential therefore the particle will be a positively charged one.

I believe you are right! If the wheels were bigger then they would add more mobility to the wagon with less effort because Allowing it to take more weight (from the wagon) allowing you to pull much easier.
Have a blessed day!
Answer:
3 × 10⁴
Explanation:
We are given two numbers, 
and 
We have to divide n₁ by n₂. We know that,
Here, n = -5 and m = -9
So on dividing we get :
Hence, on dividing n₁ by n₂ obtained number is 3 × 10⁴.
