Question

a certain particle has a weight of 30N at a place where the acceleration due to gravity is 9.8mspower-2
a)what are its mass and weight at place where the acceleration due to gravity is 3.5mspower-2?
b)What are its mass and weight at place where the acceleration due to gravity is 0?answer it surely I will mark u as brainliest

Answer 1

Answer:

Hope it helps you...

Explanation:

Answer 2

Given,

Weight of the particle=30 N

Acceleration due to gravity=$9.8 m/s^{2}$

Acceleration due to gravity on another place=$3.5 m/s^{2}$.

To find,

the mass and weight at a place where the acceleration due to gravity is $3.5 m/s^{2}$.

the mass and weight at place where the acceleration due to gravity is 0.

Solution:

• Mass is defined as the amount of matter in a space. Mass is always the same everywhere.
• The S.I. unit of mass is kilograms(Kg).
• Weight is defined as the force acting on a body due to its mass and the acceleration due to gravity. Weight changes depending upon the acceleration due to gravity.
• The S.I. unit of weight is Newton(N).

$W=mXg$

where,

W-weight of the body

m-mass of the body

g-acceleration due to gravity.

$W=mXg\\30=mX9.8\\m=\frac{30}{9.8} \\m=3.06 Kg.$

The mass of the body where the acceleration due to gravity is $9.8 m/s^{2}$ is 3.06 Kg.

a)Mass of the particle=3.06 Kg

$W=mXg\\W=3.06X3.5\\ W=10.71 N.$

The mass and weight at place where the acceleration due to gravity is $3.5 m/s^{2}$ are 3.06 Kg and 0.71 N respectively.

b)Mass will still be 3.06 Kg.

$W=mXg\\W=3.06X0\\ W=0 .$

The weight of the body will be 0 i.e. it is a weightless particle.
