give two example for each to prove that the gravitational force electrostatic force and magnetic force exist and are non contact force
Answers
Answer:
1) in magnetic force magnet has the lower to attract iron objects even from a distance
2) when u charge a comb by rubbing it on dry hair and keep it close but not touched to paper pieces they get attracted. This is electrostatic force.
3)Without touching the objects two of them are attracted to each other but the force at all times is negligible.This is gravitational force.
hope it helps you
Answer:
- GRAVITATIONAL FORCE:
WHEN WE THROW AN OBJECT IN AIR IT COMES DOWN ITSELF TO THE GROUND
WE DON'T FLY IN AIR WHILE WALKING AS GRAVITATIONAL FORCE KEEPS US ATTRACTING TOWARDS EARTH
- ELECTROSTATIC FORCE
WHEN A COMB IS RUB IN DRY HAIR,IT IS ABLE TO ATTRACT SMALL PIECES OF PAPER TOWARDS ITSELF
- MAGNETIC FORCE
WHEN A MAGNET IS BROUGHT NEAR THE COMPASS NEEDLE, COMPASS NEEDLE DEFLECTS
WHEN A MAGNET IS BROUGHT NEAR SMALL IRON FILLINGS,THESE FILLINGS GET ATTRACTED TOWARDS THE MAGNET.
