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 solid ball is suspended from the ceiling of a motor car through a light string. A transverse pulse travels at the speed 60 cm^(-1) . The acceleration of the car is nearly (g=10 ms^(-2))

A heavy ball of mass M is suspended from the ceiling of a car by a light string of mass m(mltltM). When the car is at rest, the speed of transverse waves in the string is 60,ms^(-1) . The value of a, in terms of gravitational acceleration g, is closest to :

A heavy ball of mass M is suspended from the ceiling of a car by a light string of mass m where m less than M. When the car is at rest, the speed of transverse waves in the string is 60,ms^(-1) . The value of a, in terms of gravitational acceleration g, is closest to :

In fig a sphere of mass 2 kg is suspended from the ceiling of a car which is initially at rest. Tension in the string in this situation is T_(1) The car now moves to the right with a uniform acceleration and the tension in the string is now T_(2) then: (Take g=10m//s^(2) )
