Two concentric shells of mass M1 and M2 are having radii r1 and r2. Which of the following is the correct expression for the gravitational field (I) on a mass m?
- \(I=\frac{G\left(M_{1}+M_{2}\right)}{r^{2}} \text { for } r
- \(I=\frac{G\left(M_{1}+M_{2}\right)}{r^{2}} \text { for } r
- \(I=G \frac{M_{2}}{r^{2}} \text { for } r_{1}
- \(I=\frac{G M_{1}}{r^{2}} \text { for } r_{1}
- \(I=\frac{G\left(M_{1}+M_{2}\right)}{r^{2}} \text { for } r
Answer
(D) I= G M_ 1 r^ 2 for r_ 1 <r<r_ 2
