A lift of mass 'm' is ascending with an acceleration 'a' (a $ < \mathrm{g}$ ). The tension in the cable of the lift is (g= acceleration due to gravity)
  1. $\mathrm{m}(\mathrm{g}-\mathrm{a})$
  2. $\mathrm{m}(\mathrm{g}+\mathrm{a})$
  3. $\mathrm{m}(2 \mathrm{~g}+\mathrm{a})$
  4. $\mathrm{m}(\mathrm{a}-\mathrm{g})$

Solution

m(g+a)
