force and pressure

The pressure which is exerted by air around us is known as

• force

• atmospheric pressure

• muscular force

• friction

Which Of the following is NOT an example of muscular force?

• A porter carrying a load on a wheel-barrow.

• An apple falling from a tree.

• A child riding a bicycle.

• A person drawing water from a well.

Two Objects Repel Each Other. This Repulsion Could Be Due To:

• Frictional force only

• Electrostatic force only

• Magnetic force only

• Either a magnetic or an electrostatic force

When you increase your depth under water, the water pressure on your body

• increases

• decreases

• stays the same

What decreases as you go up in the atmosphere?

• Altitude
• Atmosphere
• Meteors
• Air Pressure

How do you Calculate area?

• Pressure/force

• Force(kg)/Area(mi²)

• Area(m²)/Force(N)

Two boys A and B are applying force on a block. If the block moves towards the boy A, which one of the following statements is correct?

• Magnitude of force applied by A is greater than that of B.

• Magnitude of force applied by A is smaller than that of B.

• Net force on the block is towards B.

• Magnitude of force applied by A is equal to that of B.

When two forces act in opposite directions, then net force acting is the

• difference between two forces

• sum of two forces

• both of these

• none of these

Why did the cola caps did not move from their position? (based on the story)

• Due to atmospheric pressure

• Due to Static force

• Due to Muscular force

• Due to frictinal, electrostetic and Mangetic force

In The Electric Bell Circuit, When The Circuit Is Completed, The Hammer Strikes The Gong. Which Of The Following Force Is Responsible For The Movement Of Hammer?

• Gravitational force alone

• Electrostatic force alone

• Magnetic force alone

• Frictional force alone
