Three identical very dense masses of 7700kgeach are placed on the x axis. one mass is at x1= -100cm , one is at the origin, and one is at x2 = 420cm .

what is the magnitude of the net gravitational force fgrav on the mass at the origin due to the other two masses?

take the gravitational constant to be g = 6.67

0.00373 N

Explanation:

G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²

= Mass of the boxes

= Distance of one box from origin = 100 cm

= Distance of other box from origin = 420 cm

From the universal law of gravity

On the right hand side

The force on the center block will be

The magnitude of the net gravitational force on the mass at the origin due to the other two masses is 0.00373 N
