A 25-kg television set rests on four rubber pads, each having a height of 1.0 cm and a radius of 0.60 cm. A 200-N horizontal force is applied to the television set. How far does it move sideways? The shear modulus of rubber is 2.6 × 10⁶ N/m². A) 6.8 mm B) 3.4 mm C) 1.7 mm D) 1.5 mm E) 1.3 mm

The shear deformation can be calculated using the formula: deformation = (force * height) / (shear modulus * area). The area of one pad is π * (0.006 m)^2. The total area for four pads is 4 * π * (0.006 m)^2. Substituting the values, the deformation is approximately 1.7 mm.
