\omega_0

? (a) Increase the spring constant

k

while keeping the mass

m

unchanged (b) Decrease the mass

m

while keeping the spring constant

k

unchanged (c) Increase both

k

and

m

so that the ratio

k/m

remains unchanged (d) Decrease the spring constant

k

while keeping the mass

m

unchanged
