Answer:
9800 J
Explanation:
P.E = mgh
- m = mass
- g = gravitational acceleration
- h = height
P.E = (10.0)(9.8)(100) = 9800 J

Answer:
Explanation:
Here the rope is 10m long and making an angle of θ with the direction of canal or direction of flow of water in the canal .
sinθ = 2 / 10 = .2
θ = 11.5⁰
a )
Component of 500 N along the line perpendicular to the canal
= 500 sinθ
= 500 sin 11.5
= 100 N
b )
component of 500 N along the canal
= 500 cos 11.5
= 490 N approx .
