Explanation:
Answer:
D
Explanation:
Increasing its height to twice its original value
Answer:
- Potential Energy = mgl (1 - cosθ)
Explanation:
<h3>Given :-</h3>
- Mass of stick = m
- Length of stick = l
- Angle = θ
<h3>To Find :-</h3>
- Increase potential energy
<h3>Solution :-</h3>
✪ <u>According to the given </u><u>data</u> :-
⠀⠀⠀→ cosθ = ᵇ/ₕ
⠀⠀⠀→ cosθ = ᴬᴮ/l
⠀⠀⠀→ AB = l cosθ
❂ <u>For </u><u>Height</u> :-
⠀⠀⠀→ h = l - l cosθ
⠀⠀⠀→ h = l (1-cosθ)
☯ <u>As we know that</u>
⠀⠀⠀→ Potential Energy = mgh
⠀⠀⠀→ Potential Energy = mg × l (1-cosθ)
⠀⠀⠀→ Potential Energy = mgl (1-cosθ)
