In children's park using the part ride the visitors can be made to rotate in a vertical circle. At the top of the circle, a rider has an effective weight of magnitude `1000N`. If his actual weight is `500N` then what is the effective at eh bottom of the circle?

A

`1500N`

B

`2000N`

C

`2500N`

D

`1800N`

Text Solution

Verified by Experts

The correct Answer is:
B
At the top, effective weight
`=(mv^(2))/r-mg`
`implies1000=(mv^(2))/r-500`
or `1500=(mv^(2))/r`
`implies` At the bottom, effective weight
`=(mv^(2))/4+mtg=1500+500`
`=2000N`

Friction is a force that aids us daily, in fact so much so that we don't even pause to appreciate its important. We would not be able to wear pants or jeans without friction. We would have to live like aborigines in the jungle. The shirt is supported at our shoulders. But if we stand up the weight of our jeans is to be supported by a verticle force. The surface of our shoulders. But if we stand up the weight of our jeans is to be supported by a vertical cylinder. The force of friction acting between this curved surface and jeans balances the weight of the jeans. To understand this mathematically, let us consider a verticle man whose waist is a rigid cylinder having a circumference of 90 cm. He wears a jeans of mass 500 gm using an elastic massless belt which can be assumed to be on elastic string of forc e constant 500N//m and circumference 85cm when not extended. The coefficient of friction between waist and jeans is 0.5 . When the man stands in an elevator going up with a high acceleration, his jeans start sliding down. What can be the minimum acceleration of the elevator?
