Answer:
this is from quizlet and is similar hope it helps.
Explanation:
Which of the following statements about the force on a charged particle due to a magnetic field are not valid?
Check all that apply.
a. It depends on the strength of the external magnetic field.
b. It depends on the particle's charge.
c. It depends on the particle's velocity.
d. It acts at right angles to the direction of the particle's motion.
e. None of the above; all of these statements are valid.
Answer:
Speed only defines the magnitude of how fast an object is moving from one point to another. This is a scalar quantity (Only Value)
Velocity defines both how fast an object is moving and also in what direction the object is moving. This is a vector quantity (Value + Direction)
Solution :
a). From Newtons second law,
F = ma
The total tension force is 2T.
∴ 2T - (m + M)g = (m+ M)a
Then
b). From the person,
F = ma
T - Mg + N = Ma
or N = Ma + Mg - T
= (63 x 9.8) + (52 x 9.8) - 600
= 617.4 + 509.6 - 600
= 527 N
