Question

if a body of mass 42kg is suspended from a spring balance. what will be the force exerted on the spring balance?what is the value when it is on Jupiter (the value of g on Jupiter =23.1 m/s2) and when placed on the moon?​

Answer 1

Explanation:

1.) the force exerted on the spring balance=m*g

=42*9.8

=411.6 N

2.) if the body is placed at Jupiter, then the force exerted on the spring balance=m*g'. [g' = value of g at Jupiter]

=42*23.1

=970.2 N

3.) if the body is placed at moon, then the force exerted on the spring balance=m*g'.

[g' = g/6; accⁿ due to gravity at moon]

=42*9.8/6

=411.6/6

=68.6 N

Yaar plzzz... mark as brainliest
