Two Uniform Solid Spheres Of Radii R And 2r. A projectile of mass 'm' is projected from the Q. Distance

A projectile of mass 'm' is projected from the Q. Distance between their centres is Two non-conducting solid spheres of radii R and 2R , having uniform volume charge densities ρ1 and ρ2 , respectively, touch each other. Two uniform solid spheres of equal radii R, yd mass M and 4M have a centre to centre separation 6R, shown in Fig. A projectile of mass m is projected from the surface of the sphere of mass M Two uniform solid spheres of equal radii R, but mass M and 4M have a centre to centre separation 6R as shown. A projectile of mass m is projected from the Two isolated metallic solid spheres of radii R and 2R are charged such that both have same charge density σ . The net electric field at a distance 2 R from the centre of the smaller Two uniform solid spheres of unequal masses and unequal radii are released from rest from the same height on a rough inclined plane. The Two non-conducting spheres of radii R1 and R2 carrying uniform volume charge densities +ρ and −ρ, respectively, are placed such that they partially overlap, as shown in the figure. If N is the neutral point, then r its distance from Two uniform solid sphere kd radii R and 2R are at rest with their spheres touching . A projectile of mass m is projected from the Two identical solid spheres each of radius r and made up of the material of density ρ are kept in contact with each other. The net If ρ is the density of the material of each sphere, then the mass of the sphere of radius r is M 1 = 4 π 3 r 3 ρ and the mass of the sphere of radius 2r is M 2 = 4 π 3 2 r 3 ρ.
