A pendulum bobof masss 50 g is suspended from the ceiling of an elevator. Find the tension in the string if the elevator a. goes up with acceleration `1.2 m/s^2`, b. goes up with deceleration `1.2 m/s^2`, c. goes up with uniform velocity, d. goes down with acceleration `1.2 m/s^2` e. goes down with deceleration `1.2 m/s^2` and f. goes downwith uniform velocity.

To find the tension in the string of a pendulum bob suspended from the ceiling of an elevator under various conditions, we can analyze each scenario using Newton's second law of motion. The mass of the pendulum bob is given as 50 g, which we convert to kilograms: 1. **Convert mass to kg**: \[ m = 50 \, \text{g} = 0.05 \, \text{kg} \] 2. **Identify gravitational force**: ...
