A mass =2kg

It is suspended from a steel wire of length=l=1m

And cross-sectional area =10

to form a perpendicular arrangement

If the mass is moved to one side and released from the horizontal position of wire then find the maximum extension in the length of the wire.

Solution

A mass of 2kg is suspended from a steel wire of length =1m to form a pendulum arrangement.

Of the mass is moved to one side and released from the horizontal position of wire then
