A circus performer of mass M is walking along a wire as shown in the figure given above. The tension T in the wire is (g = acceleration due to gravity)

Options

A. approximately Mg
B. less than Mg
C. more than Mg
D. depends on whether the performer stands on one or two feet

Answer

B

Explanation

Tension in the given figure is occurring on two end of wire According to the figure.
`2T cos theta = mg`
`T=(mg)/(2 cos theta)`
`therefore` It is clearly understood that tension will be less than mg.
