A car is moving with a uniform speed on a level road. Inside the car there is a balloon filled with helium and attached to a piece of string tied to the floor. The string is observed to be vertical. The car now takes a left turn maintaining the speed on the level road. The balloon in the car will:
Correct answer: D. Be thrown to the left side
- A. Continue to remain vertical
- B. Burst while taking the curve
- C. Be thrown to the right side
- D. Be thrown to the left side
Explanation
During a left turn, the balloon filled with helium and tethered to the floor of the car will be thrown to the left side due to the moment of inertia and buoyancy effects. The lighter helium provides buoyancy, causing the balloon to move in the opposite direction of the turn. The tension in the string stabilizes its movement. Options A, B, and C are incorrect as they do not consider these factors.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.

The velocity of the projectile is increased by 2 %. If other factors remain unchanged, then what will be the percentage change in the maximum height attained?
A particle of mass 1 kg is projected at an angle of 30˚ with the horizontal with velocity v = 40 m/s. The change in linear momentum of the particle after time t = 1s will be: (g = 10 m/s2)
If the ratio of the horizontal range and the maximum height reached is 4:1. Then, if the body is thrown horizontally, what will be the projection angle?
An object launched in space having no driving power in an arbitrary direction is called:
An object is thrown in the air with an initial velocity Vi and making an angle θ with the surface of the earth. The vertical component of its velocity after time t is given by:
The velocity V of a projectile can be found by the expression:
