b. 6.0×10⁻⁸N
c. 6.9×10⁻¹⁰N
d. 9.3×10⁻¹⁰N
e. 1.5×10⁻⁷N

Answer 1

The gravitational attraction between two objects with masses of 65 kg and 87 kg that are 2.5 m apart is calculated using Newton's Law of Universal Gravitation. The result is a gravitational force of 6.0 × 10−8 N.

Step-by-step explanation:

The question is about calculating the gravitational attraction between two objects with given masses that are a specific distance apart. This calculation can be carried out using Newton's Law of Universal Gravitation. According to this law, the force of gravitational force (F) between two masses (M1 and M2) separated by a distance (R) is given by:

F = G * (M1 * M2) / R2

Where G is the gravitational constant (6.674 × 10−11 Nm2/kg2). Plugging in the masses of 65 kg and 87 kg, and a separation distance of 2.5 m, we get:

F = (6.674 × 10−11 Nm2/kg2) * (65 kg * 87 kg) / (2.5 m)2

After calculating, we find that the gravitational attraction is 6.0 × 10−8N, which corresponds to option b.
