Question

mona weighs 750 Newton on Earth on planet mars the force of gravity is 38 % of the earth what will be mona's weight on mars. What will be mona's mass on earth . (g=10m/s sq.)

Answer 1

as the ques said that weight is 38%
just do
750X38/100 = 285
hope this helps:)

Answer 2

Given:

• Mona's weight on earth = 750 N
• The force of gravity of mars compared to earth = 38%
• Acceleration due to gravity = 10m/s

To Find:

• Mona's weight on mars and her mass on earth.

Solution:

1. To find the weight of mona on mars:

The relation between the weight of mars and earth is given by,

weight on mars = weight on earth × 38% → {equation 1}

On substituting the values in equation 1 we get,

⇒ weight on mars = 750 ×38/100 = 750 × 0.38 {multiplying the terms}

⇒ weight on mars = 285 N

2. To find the mass of mona on earth:

We are using the formula,

F = m×g → {equation 2}

Where "m" is the mass and "g" is the acceleration due to gravity

On substituting the given values in equation 2 we get,

⇒ 750 = m×(10)

⇒ m = 750/10 {dividing the terms}

⇒ m = 75 Kg

∴ The weight of mona on mars = 285 N and mass on earth = 75 Kg.
