Question

Answer in detail (hint: gravitation f=GMm/r^2. g=Gm/r^2

Answer 1

Given:-

•Weight of a body on earth(W'e')=16N

To find:-

•Weight of the body on the moon(W'm')

Solution:-

We know that weight of body on the surface of moon is 1/6th of weight of a body on the surface of earth.

Thus----

=>W'm'=1/6 of W'e'

=>1/6×16

=>2.67N

Thus,weight of the body on the surface of moon is 2.67N.

Answer 2

Answer:

the required answer is option c ....2.67 N

INFORMATION:

• weight is the measure of the gravitational force acting on the body.
• here the term weight refers to the force

GIVEN:

weight of the body on the earth=force=16N

TO FIND:

the weight of body on the surface of the moon

FORMULAE:

f=GMm/r^2

g=GM/r^2

KEYS:

• F=gravitational force on earth
• F'= gravitational force on moon
• g= acceleration due to gravity on Earth
• g'= acceleration due to gravity on moon

• G= universal gravitational constant
• M= mass of the planet
• m= mass of object
• r= radius of the planet

POINT TO REMEMBER:

• acceleration due to gravity on the surface of moon is one sixth of the acceleration due to gravity on the surface of the earth.
• so the force acting on body on the moon will also be one sixth that of the earth
