To determine the limiting molar conductivity (λ₀ₘ) of water, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Concept of Limiting Molar Conductivity**: - The limiting molar conductivity of a substance is defined as the conductivity of the solution when the concentration approaches zero. For water, it can be expressed in terms of its constituent ions. 2. **Identify the Ions in Water**: ...

A small block of mass m is kept on the inclined surface of a wedge of mass M. The inclined surface of the wedge makes an angle theta with the horizontal. The wedge is kept on a frictionless rigid horizontal floor. You can neglect friction between the block and the wedge also. An external agent applies a horizontal force F on the wedge. The value of the force F so that the wedge remains at rest is F_(1) . Which of the options is incorrect?
