When a particle of charge q moves with a velocity v⃗ in a magnetic field B⃗ , the particle is acted upon by a force F⃗ exerted b
melomori [17]

Answer:

3.8\cdot 10^{-16}N

Explanation:

For a charged particle moving perpendicularly to a magnetic field, the magnitude of the force exerted on the particle is:

F=qvB

where

q is the magnitude of the charge of the particle

v is the velocity of the particle

B is the magnetic field strength

In this problem, we have

q=e=1.6\cdot 10^{-19} is the charge of the electron

v=6.0\cdot 10^6 m/s is the velocity

B=4.0\cdot 10^{-4}T is the magnetic field

Substituting into the formula, we find the force:

F=(1.6\cdot 10^{-19} C)(6.0\cdot 10^6 m/s)(4.0\cdot 10^{-4}T)=3.8\cdot 10^{-16}N

A treasure chest full of silver and gold coins is being lifted from a pirate ship to the shore using two ropes as shown in the f
stiks02 [169]

The tension in rope C is determined as 122.23 N.

<h3>Tension in rope C</h3>

The tension in rope C is calculated as follows;

B² = A² + C²

C² = B² - A²

C² = (752²) - (742²)

C² = 14,940

C = √14,940

C = 122.23 N

Thus, the tension in rope C is determined as 122.23 N.
