Inside a horizontal moving box, an experimenter finds that when an object is placed on a smooth horizontal table and is released, it moves with an acceleration of `10ms^(-2)`, in this box. If 1-kg body is suspended with a light string. The tension in the string in equilibrium position. (w.r.t. experimenter) will be (take `g=10ms^(-2)`)

A

`10ms^(-2)`

B

`10sqrt(2)ms^(-2)`

C

`20ms^(-2)`

D

Zero

Text Solution

Verified by Experts

The correct Answer is:
B
Acceleration of box =`10ms^(-1)`
Inside the box force acting on bob
` `
`T=sqrt((mg^2)+(ma^2))`
