Hello!
I believe the answer is false. Please let me know if you have any other questions. Have a bless day!

Potential Energy can be quantified as mass times gravity times height (PE=m*g*h). The unit for mass should be either kilogram or pound mass depending on the unit system. Gravity is a constant, 9.81 m/s² in SI units or 32.2 ft/sec² in English units.
This is the correct answer to your question, "BC shows zero acceleration, and CD shows negative acceleration".
Answer:
The winding density of the solenoid, n = 104 turns/m
Explanation:
Given that,
Length of the solenoid, l = 0.7 m
Radius of the circular cross section, r = 5 cm = 0.05 m
Energy stored in the solenoid,
Current, I = 0.4 A
To find,
The winding density of the solenoid.
Solution,
The expression for the energy stored in the solenoid is given by :
Where
L is the self inductance of the solenoid
n is the winding density of the solenoid
n = 104 turns/m
So, the winding density of the solenoid is 104 turns/m
