Given data
*The given mass of the classmate is m = 65 kg
*The weight of the table is W = 0 N
The formula for the mass of the table is given as
![M=(W)/(g)](https://img.qammunity.org/2023/formulas/physics/college/hzzx2johbctgy1e7fcnu75huxr8zx60axn.png)
*Here 'g' is the acceleration due to gravity
Substitute the known values in the above expression as
![\begin{gathered} M=\frac{0\text{ }}{9.8} \\ =0\text{ kg} \end{gathered}](https://img.qammunity.org/2023/formulas/physics/college/1abigfoxgputptxl3a0v4ixszq90w2zm7g.png)
Hence, the mass of the table is M = 0 kg
