NEET · Physics · STD 11 - 7. gravitation
In a gravitational field, the gravitational potential is given by, \(V =-\frac{ K }{ x }( J / kg )\). The gravitational field intensity at point \((2,0,3)\,m\) is
- A \(+\frac{ K }{2}\)
- B \(-\frac{ K }{2}\)
- C \(-\frac{K}{4}\)
- D \(+\frac{K}{4}\)
Answer & Solution
Correct Answer
(C) \(-\frac{K}{4}\)
Step-by-step Solution
Detailed explanation
\(V=-\frac{K}{x}\) \(E_x =-\frac{d V}{d x}=K \frac{d\left(x^{-1}\right)}{d x}\)
