hello your question lacks the required question attached below is the missing diagram
Forces in GJ = -4.4444 i.e. 4.4444 tons
Forces in IG = 15.382 tons ( T )
Explanation:
Forces in GJ = -4.4444 i.e. 4.4444 tons
Forces in IG = 15.382 tons ( T )
attached below is the detailed solution
Answer: T= 159.3N
Explanation:
The total Tension on the rope at this point=
Sum of the weight of the ball + the centripetal force on the ball
T= W+ mv^2/r
Where T is tension, W is weight of the ball, m is mass of the ball, r is radius of rotation, v is the velocity of rotation. g= acceleration due to gravity
W= 100N
m= W/g= 100/9.8 = 10.2kg
v= 5m/s
r= 4.3m
Therefore,
T= 100 + 10.2×5^2/4.3
T= 100 + 59.3
T= 159.3N
