Which row shows two scalar quantities? A gravitational potential gravitational field strength B mass gravitational potential C gravitational field strength weight D weight gravitational potential - AQA - A-Level Physics - Question 8 - 2019 - Paper 2

To determine which row shows two scalar quantities, we first need to identify the nature of each quantity listed:

1. Gravitational Potential: This is a scalar quantity because it has a magnitude but no direction.
2. Gravitational Field Strength: This is a vector quantity as it has both magnitude and direction.
3. Mass: This is a scalar quantity.
4. Weight: This is a vector quantity since it depends on gravitational acceleration which has a direction.

With this understanding, we can analyze the rows:

• Row A: One scalar and one vector (not valid).
• Row B: Two scalars (valid).
• Row C: One scalar and one vector (not valid).
• Row D: One scalar and one vector (not valid).

Therefore, the correct answer is B (mass and gravitational potential), as both are scalar quantities.
