Question

The weight of the man on Earth is 150 N and the Certain Planet is 25N . Taking g= 10 m/s² on earth a) find the mass of the man on earth and on the planet .
B) find the acceleration due to gravity on the planet

Answer 1

First of all,

*W = Weight

*M = Mass

*N = Newton

*G = Acceleration due to gravity

According to question,

The weight of the man on earth is 150N.

[ 1st question ]

150N = M × 10

M => 150/10

M => 15kg

We know that,

▪️ Mass remains same at any place. ▪️

➡️ Mass of the man is 15 kg on earth and on certain planet will be also 15kg.

⚫️ So, 15 Kg is the mass of the man on earth and on the planet . ⚫️

[ First questions answer = 15kg ]

[2nd question]

W=mg

g= W/ m

G =25/15

⚫️ The acceleration due to gravity is 1.67 m/s^2 ⚫️

[2nd question answer is 1.68 m / s^2 ]
