A$10.$ A string with a fixed frequency vibrator at one end is undergoing resonance with $4$ antinodes when under tension $\backslash (\backslash$mathrm$\{$T$\}\_\{1\}\backslash ).$ When the tension is slowly increased, the resonance condition disappears until tension $\backslash (\backslash$mathrm$\{$T$\}\_\{2\}\backslash )$ is reached, and no resonances occur between these two tensions. How many antinodes are there in this new resonance?

A$)2$

C$)4$

D$)5$

E$)6$
