Question

Attach a suitable mass to spring balance so
that it stretches by about half is capacity.
Now whirl the spring balance so that the
mass performs a horizontal motion. You will
notice that the balance now reads more mass
for the same mass. Can you explain this?​

Answer 1

Answer:

Physical balance is based on comparison. So, even though the actual apparent weight increases but when compared with the standard weights, it will show the original reading.

For a mass weighed by spring balance, the mass experiences a psuedo force in the downward direction and hence, effective weight in the frame of reference of the lift increases.
