Inside a horizontally moving box, an experimenter finds that when an object is placed on a smooth horizontal plane and is released, it moves with an acceleration of 10 `m//s^2`. In this box if 1 kg body is suspended with a light string, find the tension in the string in equilibrium position (w.r.t experimenter) (g = `10m//s^2`)

Explanation

acceleration of box `=10 m//s^(2)`

`T = sqrt((mg)^(2) + (ma)^(2))`
`T = sqrt(10^(2) + 10)`
`T=10sqrt(2)` N
