If \(a,b\) are arbitrary constants, then the differential equation corresponding to family \[ y=ax^2-2abx+ab^2 \] is
A body is allowed to fall freely from a height of 120 m from the ground and at the same moment another ball is thrown vertically upwards from the ground such that it reaches a maximum height of 180 m. The time taken for the two bodies to meet is (Acceleration due to gravity $=10~ms^{-2}$)
A boy can swim with a speed of \(18\) kmph in still water. If the speed of the water in a river is \(10.8\) kmph, then the average speed of the boy in travelling downstream for a distance of \(120\) m and upstream for a distance of \(90\) m over the river is
A body is thrown vertically upwards from earth with velocity \(60\text{ ms}^{-1}\). The ratio of displacements during first, second and third seconds is (\(g=10\text{ ms}^{-2}\))
Two trains A and B are moving in the same direction with velocities \(V_A\) and \(V_B\) respectively and a third train C is moving in opposite direction. If velocity of C with respect to B is twice the velocity of A with respect to B, then velocity of A with respect to C is:
A body starts from rest and moves with uniform acceleration. The ratio of distance covered in 4th and 3rd seconds is:
Two balls P and Q are thrown vertically upwards simultaneously from the ground with velocities $20\ \text{m s}^{-1}$ and $35\ \text{m s}^{-1}$ respectively. The distance between the two balls when the velocity of P becomes zero is: (g = $10\ \text{m s}^{-2}$)}
A car and a motor cycle start their motion from the same point with initial velocities \(23.7\text{ ms}^{-1}\) and zero respectively. If the accelerations of the motor cycle and car are \(3.8\text{ ms}^{-2}\) and zero respectively, then their relative velocity when the motor cycle crosses the car is:
If the displacement of a body moving with constant acceleration in a straight line path in the first four seconds of time is 56 m and its displacement in the fourth second of the motion is 17 m, then the average velocity of the body during sixth second of its motion is
The force \(F\) acting on a particle in terms of its distance \(x\) from a fixed point is given by \[ F=\frac{A}{B+x^{1.5}}. \] If the dimensional formula of \(AB\) is \[ [M^aL^bT^c], \] then the value of \(a+b+c\) is
Statement-I: When two quantities are multiplied, the relative error in the result is the sum of the relative errors in the quantities.
Statement-II: When two quantities are divided, the relative error in the result is the difference of the relative errors in the quantities.
If the errors in the measurements of diameter, length and electrical resistance of a wire are 1%, 0.5% and 2% respectively, then percentage error in the determination of the resistivity of material of the wire is:
