Question

$5kg$ and $10kg$ spheres are $1m$ apart. At what distance from the $5kg$ block will the gravitation field intensity be zero ?

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

Answer 1

Answer: (A)

$0.4m$

$\frac{G{M}_1}{x^2}=\frac{G{M}_2}{(1-x{)}^2}or\frac{1-x}{x}=\frac{\sqrt{2}}{1}$
or $x=\frac{1}{\sqrt{2}+1}=0.4m$
