Answer:
a)T= mg/2
b) T = 31. 88 N
c)Tension will increase
Explanation:
Given that m= 6.5 Kg
a)
The force due to gravity = m g
The tension in the chain = T
The total tension = 2 T
By balancing force in vertical direction
2 T = m g
T= mg/2
b)
2 T = m g
2 x T = 6.5 x 9.81
T = 31. 88 N
c)
Lets take angle made by chain is θ
So the total tension in vertical direction = 2 T cos θ
2 T cos θ = m g
T= mg/(2cos θ)
It means that tension will increase because cos θ is always less than 1.
