Question

1. choose the best answer. which of these has the greater gravitational pull? a b

Explanation:

Step1: Recall Gravitational Force Formula

The gravitational force between two objects is given by \( F = G\frac{m_1m_2}{r^2} \), but for an object's gravitational pull (weight) near Earth, \( F = mg \), and mass is related to volume (for same density, \( m=
ho V \), \( V=\frac{4}{3}\pi r^3 \) for a sphere). Larger radius (size) means larger mass (if same density).

Step2: Compare Sizes of A and B

From the image, sphere A appears larger (bigger radius) than sphere B. So A has more mass. Since gravitational pull (weight) is proportional to mass (\( F = mg \), \( g \) constant near Earth), a larger mass means a greater gravitational pull.

Answer:

A. (the option corresponding to the larger sphere, which has greater mass and thus greater gravitational pull)
