AUGUST MONTHLY TEST- 11th PHYSICS ONE MARK-2021

When a car takes a sudden left turn in

the curved road, passengers are pushed

towards the right due to

• inertia of direction

• Inertia of motion

• Inertia of rest

• Inertia of absence

Force acting on the particle moving

with constant speed is

• always zero

• need not be zero

• always non zero

• cannot be concluded

Two masses m1

and m2 are experiencing

the same force where m1<m2 . The ratio

of their acceleration a1/a2 is

• 1

• less then one

• greater than one

• all the three cases

A vehicle is moving along the positive

x direction, if sudden brake is applied, then

• frictional force acting on the

  vehicle is along negative x direction

• frictional force acting on the

  vehicle is along positive x direction

• no frictional force acts on the vehicle

• frictional force acts in downward direction

When the object is moving at constant

velocity on the rough surface,

• net force on the object is zero

• no force acts on the object

• only external force acts on the

  object

• only kinetic friction acts on the object

A book is at rest on the table which

exerts a normal force on the book. If

this force is considered as reaction

force, what is the action force according Newtowns third law

• Gravitational force exerted by

  Earth on the book

• Gravitational force exerted by the

  book on Earth

• Normal force exerted by the book

  on the table

• ) None of the above

The unit of impulse is ------?

• Ns

• Nm

• Nc

• Nw

we can derive the law

of conservation of total linear momentum using laws-----?

• Newtowns first law

• Newtowns second law

• Newtowns third law

• Newtowns first and second law

The ropes used in conveyor

belts -------motion work for longer

duration than those of cranes and lifts -------motion?

• a)Linear motion

• b)Vertical motion

• c)Horizontal motion

• b and c

The following systematic steps are followed

for developing the free body diagram:

• Identify the forces acting on the object.

• Represent the object as a point.

• Draw the vectors representing the forces

  acting on the object.

• All the above
