Step 1: {Apply shell theorem}
The shell theorem states that a uniform spherical shell of mass exerts zero net gravitational force on a particle inside it.
Step 2: {Explain force cancellation}
Forces from opposite sides of the shell cancel out due to symmetry, leaving: Net gravitational force = 0.
Thus, the correct answer is zero.
Among the following, the correct statements are:
Statement I – Nature of Saline (Ionic) Hydrides
Statement II – Volatility of Saline Hydrides
Statement III – Nature of Electron-Precise Hydrides
Statement IV – Formula of Chromium Hydride
