A string of negligible mass going over a clamped pulley of mass m supports a block of mass M as shown in the figure. The force on the pulley by the clamp is given by A. `sqrt2mg`B. `sqrt2mg`C. `[sqrt((M + m)^(2) + m^(2))]g`D. `[sqrt((M + m)^(2) + m^(2))]g` |

Answer» Correct Answer - c Force on the pulley by the clamp = resultant of `T = (M + m)` g and mg acting along horizontal and vertical directions respectively `= sqrt([(M + m) g]^(2) + (mg)^(2))` `=[sqrt((M + m)^(2) + m^(2)]]g` . |
