A positively charged particle is located at point A and is stationary. The direction of the magnetic force on the particle is:
1 answer:
Complete Question
The complete question is shown on the first uploaded image
Answer:
The correct option is option 5
Explanation:
From the question we are told that the positive particle is stationary hence the velocity is zero
Generally the magnetic force acting on the particle is mathematically represented as
Here X represents a cross product
So since the velocity is zero

Answer:
<em>The final speed of the vehicle is 36 m/s</em>
Explanation:
<u>Uniform Acceleration</u>
When an object changes its velocity at the same rate, the acceleration is constant.
The relation between the initial and final speeds is:
Where:
vf = Final speed
vo = Initial speed
a = Constant acceleration
t = Elapsed time
The vehicle starts from rest (vo=0) and accelerates at a=4.5 m/s2 for t=8 seconds. The final speed is:
The final speed of the vehicle is 36 m/s
