Q95 / 200 · NEET 2021 · Physics

If E and G respectively denote energy and gravitational constant, then EG has the dimensions of:

  • A
    [M]L0T0
  • B
    [M]L-1T-1
  • Correct answer
    C
    M2L-1T0
  • D
    M2L-2T-1

Solution

Dimensional Formulas,

Energy, [E]=M1L2T-2

Gravitational constant

[G]=Fr2M2=M1L1T-2×L2M2

[G]=M-1L3T-2

Now,

EG=ML2T-2M-1L3T-2=M2L-1T0

Correct option (3)

Hence, the correct answer is option: 'C'.
