3 Physics questions from this JEE Main paper
- Q45.A body of mass m = 10 kg is attached to one end of a wire of length 0.3 m. The maximum angular speed (in rad s–1) with which it can be rotated about its other end in space station is : (Breaking stress of wire = 4.8 × 107 Nm–2 and area of…Physics · Rotational Motion · Numerical
- Q47.One end of a straight uniform 1m long bar is pivoted on horizontal table. It is released from rest when it makes an angle 30º from the horizontal (see figure). Its angular speed when it hits the table is given as s-1, where n is… Includes diagramPhysics · Rotational Motion · Numerical
- Q49.Three solid spheres each of mass m and diameter d are stuck together such that the lines connecting the centres form an equilateral triangle of side of length d. The ratio I0/IA of moment of inertia I0 of the system about an axis passing… Includes diagramPhysics · Rotational Motion · MCQ
