Answer:
The frequency of the oscillations in terms of fo will be f2=fo/3
E xplanation:
T=
=1:3
⇒f2=fo\3
Here frequency f is inversely poportional to square root of mass m.
so the value of remainder of frequency f2 and fo is equal to 1:3.
⇒ =
⇒ = 1:3
⇒f2=
Answer:
All points to the left of zero are negative
