The charge density of the sheet is 1.384×10⁻⁷C/m².
Charge density is defined as the charge per unit area.
The sheet is a square of length l=17 cm.
Calculate the area A of the sheet .

The charge Q on the sheet is

The charge density σ is given by,

Substitute 4×10⁻⁹C for Q and 0.0289 m² for A.

Thus, the charge density of the sheet is <u>1.384×10⁻⁷C/m².</u>
Answer:
Please make image clearer
Explanation:
You are too far back please move closer to the paper
Taking right movement to be positive means leftward movement is negative.
Hence we have a deceleration of



Using this 'suvat' equation

we can determine the initial velocity



Hence the initial velocity is 13.0 meters per seconds
Answer:
The metal atoms in the wire can't move, but their outer electrons can. The force pushes those electrons and they move to further parts of the wire, trying to reach the other end. As the electrons move away, new electrons flow into the wire through the battery to take their place.
