Question

Length is measured in metre and time in second as usual. But a new unit of mass is so chosen that G=1. This new unit of mass is equal to (A) 1.5 × 107 kg (B) 1.5 × 1010 kg (C) 6.67 × 10-11 kg (D) 6.67 × 10-8 kg

New unit of mass is (1/6.67 × 10-11) kg i.e., 1.5 × 1010 kg

Q. Length is measured in metre and time in second as usual. But a new unit of mass is so chosen that $G = 1$ . This new unit of mass is equal to

$1.5 \times 1 0^{7} k g$

$1.5 \times 1 0^{10} k g$

$6.67 \times 1 0^{- 11} k g$

$6.67 \times 1 0^{- 8} k g$

New unit of mass is $\frac{1}{6.67 \times 1 0 ^{- 11}} k g$
i.e., $1.5 \times 1 0^{10} k g$

Q. Length is measured in metre and time in second as usual. But a new unit of mass is so chosen that G=1. This new unit of mass is equal to

1.5×107kg

1.5×1010kg

6.67×10−11kg

6.67×10−8kg
