Question

Check by the method of dimensions weather the following equation are correct. A) E=mc^2
B) T=2π√I/g

Answer 1

Answer:

Explanation: E=mc²

Where 'E' is the energy,"m" is the mass,"c" is speed of light...

Mass=[M],speed of light=[LT^-1]²

W=[ML²T-²] hence these are the dimensions of Work. As work is a form of energy so [ML²T^-2]=[ML²T^-2]

Both are dimensionally correct
