1. False
2. Positive
I’m just joking I don’t know the answersss
The answer is 12 J
because you have to multiply the two together. hope it helps
Answer:
v = 5.75 x 10⁶ m/s
Explanation:
The radius (r) of the circular orbit taken by a charged particle is related to its speed perpendicular to a magnetic field of strength B, and is given by
r =
--------------(i)
Where,
q = charge of the particle
m = mass of the particle
Making v subject of the formula in equation (i) above gives
v =
-------------------(ii)
Given;
r = 20cm = 0.2m
B = 0.3T
v = unknown
q = charge of proton = 1.6 x 10⁻¹⁹ C
m = mass of the proton = 1.67 x 10⁻²⁷kg
Substitute the values of m, q, B and r into equation (ii) above to get;
v = 
Solving for v gives:
v = 5.75 x 10⁶ m/s
Therefore, the velocity of the proton is 5.75 x 10⁶ m/s
Answer:
Ratio is 7.58
Explanation:
At the bottom of the circle, the net force is given by
where m is mass of plane, v is the speed of plane, r is vertical circle radius

Since W=mg, dividing left side by W and right side by mg we obtain


=7.578096
=7.58
Considering that
=7.58 which is greater than 2, the pilot is advised to wear the anti-G suit
