A ball is suspended by a cord from the ceilling of a motor car What will be the effect on the position of the ball , if (i) the car is moving with unifrom velocity (ii) car is accelerated (iii) car is turning towards left ?

A small sphere is suspended by a string from the ceiling of a car. If the car beings to move with a constant acceleration a, the inclination of the string to the vertical is:

A heavy ball is suspended from the ceilling of a motor can through a light strig. A transverse pulse travels at a speed of 50 cm//s on the strin when the car is at rest and 52 cm//s when the car accelerates on a horizontal road. Then acceleration of the car is : (Take g = 10 m//s^(2) .)

A heavy ball is suspended from the ceiling of a motor car through a light string. A transverse pulse travels at a speed of 60 cm s^-1 on the string when the car is at rest and 62 cm s^-1 when the car accelerates on a horizontal road. Find the acceleration of the car. Take g = 10 ms^-2

A small ball is suspended by a string from the ceiling of a car. As the car accelerates at a rate ‘a’ the string makes an angle 'a' with the vertical in equilibrium. Then the tension in the string is :

A plumb line is suspended from a celling of a car moving with horizontal acceleration of a. What will be the angle of inclination with vertical?

A plumb line is suspended from a ceiling of a car moving with horizontal acceleration of a . What will be the angle of inclination with vertical

A plumb bob is hanging from the ceiling of car. If the car move with acceleration a, the angle made by the string with the vertical is

A ball is suspended from the accelerating car by two cords 'A' and 'B' . The acceleration 'a' of the car which will cause the tension in 'A' to be twice the tension in B, is

A boy throws a ball vertically upwards froma moving open car on a horizontal straight road (i) The ball will fall behind the boy, if car is accelerating (ii) The ball will fall in front of the boy, if car is decelerating (iii) The ball will fall in the hands of boy if car is moving with uniform velocity (iv) The path of ball as seen by the boy will be vertical straight line if car is moning uniformly (v) The path of ball as seen by observer on ground will be parabola
