Two blocks of masses $m_1$ and $m_2\left(m_1>m_2\right)$ are connected by a massless threads, that passes over a massless smooth pulley. The pulley is suspended from the ceiling of an elevator. Now the elevator moves up with uniform velocity ${\mathbf{V}}_0$. Now, select the correct options.

Magnitude of acceleration of $m_1$ with respect to ground is greater than $\frac{\left(m_1-m_2\right)g}{m_1+m_2}$

Magnitude of acceleration of ${\mathrm{m}}_1$ with respect to ground is equal to $\frac{\left(m_1-m_2\right)g}{m_1+m_2}$

Tension in the thread that connects $m_1$ and $m_2$ is equal to $\frac{2m_1{m}_{2}g}{m_1+m_2}$

 Tension in the thread that connects $m_1$ and $m_2$ is greater than $\frac{2m_1{m}_{2}g}{m_1+m_2}$
