GRAVITATION

THE EARTH AND MOON ARE ATTRACTED TO EACH OTHER BY A GRAVITATIONAL FORCE.THE EARTH ATTRACTS WITH A FORCE THAT IS:

• MORE THAN THAT EXCERTED BY MOON

• SAME AS THAT EXCERTED BY MOON

• LESS THAN THAT EXCERTED BY MOON

• NOT RELATED TO THAT EXCERTED BY MOON

A STONE IS RELEASED FROM THE TOP OF A TOWER OF HEIGHT 19.6m. THEN IT'S FINAL VELOCITY JUST BEFORE TOUCHING THE GROUND WILL BE.

• 384.16 m/s

• 196 m/s

• 19.6 m/s

• 3819.4

CHOSE THE CORRECT UNIT FOR THE RELATIVE DENSITY AMONG THE FOLLOWING:

• kg/cm

• kg/mm

• kg/km

• unitless

AN OBJECT HAVING MASS EQUAL TO 350g OCCUPIES 200cm(cube) OF THE SPACE.WHEN THIS OBJECT IS THROWN INTO A RIVER WHAT WILL BE THE CONDITION OF THIS OBJECT THERE ?

• IT WILL FLOAT ON THE SURFACE OF WATER

• IT WILL FLOAT FULLY SUBMERGED IN THE LIQUID

• IT WILL SINK IN THE LIQUID

• IT WILL FLOAT PARTIALLY SUBMERGED IN THE LIQUID

THE SCHOOL BAGS ARE GENERALLY PROVIDED WITH BROAD STRIPS BECAUSE ?

• IT WILL SPREAD THE FORCE OF THE BAG OVER THE LARGE AREA OF THE SHOULDER OF THE CHILD PRODUCING LARGE PRESSURE

• IT WILL SPREAD THE FORCE OF THE BAG OVER THE LARGE AREA OF THE SHOULDER OF THE CHILD PRODUCING LESS PRESSURE

• IT HAS BECOME A TREND AMONG THE STUDENTS TO CARRY THE BAGS WITH WIDE STRIPS

• NONE OF THE ABOVE

TWO OBJECTS OF DIFFERENT MASSES FALLING FREELY NEAR THE SURFACE OF MOON WOULD:

• HAVE DIFFERENT ACCELERATIONS

• UNDERGO A CHANGE IN THEIR INERTIA

• HAVE SAME VELOCITIES AT ANY INSTANT

• EXPERIENCE FORCES OF SAME MAGNITUDE

THE VALUE OF ACCELERATION DUE TO GRAVITY

• IS SAME ON THE EQUATOR AND POLES

• IS LEAST ON POLES

• IS LEAST ON EQUATOR

• INCREASES FROM POLE TO EQUATOR

WHAT IS THE VALUE OF UNIVERSAL GRAVITATIONAL CONSTANT ON MOON IF ITS VALUE IS G ON EARTH

• G

• G/6

• G/2

• G/3

THE ACCELARATION DUE TO GRAVITY VARIES ON EARTH WITH

• DISTANCE FROM EQUATOR

• ALTITUDE

• MASS OF AN OBJECT

• (A) AND (B)

WHAT CAUSES TINDAL WAVES IN THE SEA ?

• GRAVITATION EFFECT ON THE EARTH BY MOON

• GRAVITATIONAL EFFECT ON THE EARTH BY THE SUN

• THE ATMOSPHERIC IMPACT OF EARTH

• NONE OF THESE
