Question

5 kg and 10 kg spheres are 1 m apart. Where the gravitation field intensity be zero from 5 kg block.

• A. 0.4 m
• B. 0.3 m
• C. 0.25 m
• D. 0.35 m

Answer 1

Answer: (B)

0.3 m

Answer 2

$\frac { \mathrm { GM } _ { 1 } } { \mathrm { x } ^ { 2 } } = \frac { \mathrm { GM } _ { 2 } } { ( 1 - \mathrm { x } ) ^ { 2 } }$ or $\frac { 1 - \mathrm { x } } { \mathrm { x } } = \frac { \sqrt { 2 } } { 1 }$or x = $\frac { 1 } { \sqrt { 2 } + 1 } = 0.4 \mathrm {~m}$
