According to Newton’s Law of Gravitation: 𝐹 =𝐺⋅𝑚1⋅𝑚2/𝑟2 If both masses 𝑚1 and 𝑚2 are doubled, the new force becomes: 𝐹′=𝐺⋅(2𝑚1)⋅(2𝑚2)/𝑟2 =4⋅𝐹=4⋅F So, the force increases by a factor of 4.
Two masses are separated by a distance r. If both masses are doubled, the force of interaction between the two masses changes by a factor of ______?
