Question

A physics scholar took two spring balances S1 and S2 that are calibrated on the surface of the moon and the earth respectively is unweighted your body using both S1 and S2 in given place on the surface of the earth determine the ratio of the readings what is the ratio​

Answer 1

Answer:

The mass is stationary with respect to the lift  calculate the mass of the block m=30

Explanation:

Let assume that the first spring balance is S1 and the second spring balance is  S2.

Given S1=90kg and S2=30kg.

The lift is  accelerating upwards with acceleration 10 m/s

Now as the free body diagram we have total of two equation.

Let the acceleration mass is ma and mass fopr the gravitational field is mg

S1= 90 - mg = ma....................(1)

and S2= mg - 30= ma.....................(2)

So, adding the two equation is we get

60g = 2ma

=> m=30 (∵g=a)

Answer 2

Answer:

1:1 is the answer!

Explanation:

Here, the readings on the spring balances remain the same as the weight of he same object is measured. So, each spring balance shows same reading. Hence, the ratio is 1:1.
