The diagram a a simple pendulum consisting of a mas M suspended by a thin string

Question

The diagram a a simple pendulum consisting of a mas M suspended by a thin string. The magnitude of the tension is T (Note T is the tension here not the period!) The mass shows swings back and forth between eo and eo. (For visual aid, see fig 5.15 of the 5th edition of Serway and Jewett's "Principles of Physics" v T depends on e. v The vertical component of tension is constant. v T is greater than Mg for e eo. T Mg at some angle between eo and eo. T is largest at the bottom (e 0). T T equals Mg when e eo v T is smallest when 0 eo. Submit Answer Tries 0/10

Explanation / Answer

Here, Tcos =mg

       => T = mg/cos

This shows that

(1) T depends on = true

(2) Vertical component of tension is constant = true

(3) T is greater than mg for =o = true

(4) T=mg for some angle between -o and o = true      (at = 0 degree)

(5) T is largest at bottom = false

(6) T equals mg when = o = false

(7) T is smallest when =+- o   = false
