To calculate the tension in the horizontal string of a pendulum with a bob mass of 1.8 kg and a string length of 2.3 m, the forces acting on the bob must be analyzed. The pendulum is held at a 30-degree angle from the vertical, creating a scenario where both gravitational and tension forces are at play. The relevant equations involve resolving the forces into components and applying trigonometric principles to find the tension. The forum emphasizes the importance of showing work and understanding the problem rather than simply seeking answers. Accurate calculations require a clear understanding of the forces and vectors involved in the pendulum's motion.

A bob of mass 1.8 kg attached to a string of length 2.3 m. The pendulum is held at an angle of 30 degrees from the vertical by a horizontal string attached to a wall.

What is the tension in the horizontal string?

Thread 'Magnitude of buoyant force in fluids of different densities'

The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
