The tension in a string holding a solid block below the surface of a liquid (where ρliquid > ρblock) as in shown in the figure is T when the system is at rest.
Then what will be the tension in the string if the system has upward acceleration a?
Then what will be the tension in the string if the system has upward acceleration a?
- \(\mathrm{T}\left(1-\frac{\mathrm{a}}{\mathrm{~g}}\right)\)
- \(\mathrm{T}\left(1+\frac{\mathrm{a}}{\mathrm{~g}}\right)\)
- \(\mathrm{T}\left(\frac{\mathrm{a}}{\mathrm{~g}}-1\right)\)
- \(\frac{\mathrm{a}}{\mathrm{~g}} \mathrm{~T}\)
Answer
(B) T (1+ a ~g )
