Question

Solve this!!! 50 points!!!

Answer 1

Explanation:

Given,

mass = 10 kg

length = 10 m

ū = 0.2

Force = 20 N

Tension in the mid point of the chain

f = μN

= 0.2 × 0.2 N

= 2/10 × 20 = 4

and

f′ = 10/10 N

= 1 N

Tension

= 4 + 1

= 5 N

Answer 2

Answer:

Correct option is  D ) 5N

mass=10kg

length=10m

μ=0.2

Force=20N

Tension in the mid point of the chain

f=μN=0.2×0.2N=  2/10 ×20=4

and f  ′  =  10 /10

N=1N

Tension =4+1

=5N
