The correct Answer is:
To determine whether the string will break while whirling a body of mass 0.5 kg at a velocity of 2 m/s using a 0.5 m long string, we need to calculate the centripetal force acting on the body and compare it with the maximum tension the string can withstand. ### Step-by-Step Solution: **Step 1: Identify the given values.** - Mass of the body (m) = 0.5 kg - Velocity (v) = 2 m/s - Length of the string (radius, r) = 0.5 m - Maximum tension the string can withstand (T_max) = 15 N **Step 2: Calculate the centripetal force (F_c).** The formula for centripetal force is given by: \[ F_c = \frac{mv^2}{r} \] Substituting the known values: \[ F_c = \frac{0.5 \, \text{kg} \times (2 \, \text{m/s})^2}{0.5 \, \text{m}} \] Calculating the value: \[ F_c = \frac{0.5 \times 4}{0.5} = \frac{2}{0.5} = 4 \, \text{N} \] **Step 3: Compare the centripetal force with the maximum tension.** - The calculated centripetal force (F_c) = 4 N - The maximum tension (T_max) = 15 N Since \( F_c < T_{max} \): \[ 4 \, \text{N} < 15 \, \text{N} \] **Step 4: Conclusion.** The tension in the string (which provides the centripetal force) is less than the maximum tension the string can withstand. Therefore, the string will not break. ### Final Answer: The string will not break. ---
