A spherical shell is cut into two pieces along a chord as shown in the figure. P is a point on the plane of the chord. The gravitational field at P due to the upper part is I1 and that due to the lower part is. I2 What is the relation between them :
Answer & explanation
Correct answer: option 2
Intensity at P due to upper part I1 and Intensity at P due to lower part = l2 .
Net Intensity at p due to spherical shell :
\(I_1 + I_2 = 0\)
\(\Rightarrow |I_1| = |I_2|\)
