Question

find the value of 'x'​

Answer 1

Answer:

x = +r. or -r

Step-by-step explanation:

cancelling - ve sign, G, M, m in numerator and one R in denominator on both sides we get following equation.

$\frac{3 {r}^{2} - {x}^{2} }{2 {r}^{2} } = \frac{4}{3} \\ 9 {r}^{2} - 3 {x}^{2} = 8 {r}^{2} \\ {x}^{2} = 3 {r}^{2} \\ x = +√3 r \: or \: -√3 r$
