A body of mass 'm' attached at the end of a string is just completing the loop in a vertical circle. The apparent weight of the body at the lowest point in its path is
(\(g\) = gravitational acceleration)
A stone of mass \(40\) g is tied to a light inextensible string of length \(50\) cm and whirled in a vertical circle at the rate of \(30\) revolutions per minute. The tension in the string when it is at the lowest point of the circle is
(Take gravitational acceleration, \(g = 10\,\text{m/s}^2\) and \(π^2 = 10\))
Two stones of masses \(m\) and \(3m\) are whirled in horizontal circles, the heavier one in a radius \(\frac{r}{3}\) and the lighter one in radius \(r\). When both the stones experience same centripetal forces, the tangential speed of lighter stone is '\(n\)' times that of the value of heavier stone. The value of '\(n\)' is
Radius of gyration of a thin uniform circular disc about the axis passing through its centre and perpendicular to its plane is \(K_c\). Radius of gyration of the same disc about a diamter of the disc is \(K_d\). the ratio \(K_d:K_c\) is
A particle describes a horizontal circle of radius 'r' in conical funnel with smooth inner surface with a speed of \(0.5\) m/s. The height of the plane of the circle from the vertex of the funnel is (acceleration due to gravity, \(g = 10\,\text{m/s}^2\))
A bucket containing water is revolved in vertical circle of radius r. To prevent the water from falling down, the period of revolution required is (\(g\) = gravitational acceleration)
A car of mass m is crossing the convex bridge of radius of curvature R with speed V. At the highest point the thrust is (\(g\) = gravitational acceleration)
Determine the centripetal force acting on a \(1000\,\text{kg}\) car moving at \(20\,\text{m/s}\) around a curve of radius \(50\,\text{m}\).
A body of mass 2 kg is moving in a circular path of radius 3 m with a constant speed of 6 m/s. What is the centripetal force acting on the body?
In case of well of death which is a vertical cylindrical wall of radius ' \(r\) ' inside which vehicle is driven in horizontal circles. If ' \(m\) ' is mass of vehicle, ' \(V\) ' is the velocity and ' \(\mu_s\) ' is the coefficient of static friction between the wheels of vehicle and walls then correct relation is [ \(g\) = acceleration due to gravity]
A particle moves in a circular orbit of radius 'r' under a central attractive force, \( F = -\frac{k}{r} \), where k is a constant. The periodic time of its motion is proportional to
