A force of 100 dynes acts on mass of 5 gm for 10 sec. Solved: A force of 50 dynes is applied on a body of mass 5g which is at rest for an interval 1 sec. Answer. If the same force acts on a body of mass 1.5 kg the acceleration produced in it is: A. edison25 edison25 Change in velocity (v-u) will be 2 metre per second New questions in Physics. The detailed, step-by-step solutions will help you understand the concepts better and clear your confusions, if any. 1.0 m/s 2: C. 5.0 m/s 2: D. 7.0 m/s 2 . Answer: Force F = 50 dynes ... A force of 100 N gives a body of mass m}, an acceleration of 5 ms/s 2. SI unit of force :-We know, F = ma. Weight is a measure of force not mass (weight = m g) and is expressed in units of dynes, N, or lb. What is the velocity of a body of mass 5 gm if a force of 100 dynes acts on the body for 10 seconds? Inertia. A force of 600 dynes acts on a glass ball of mass 200 g for 12 s. If initially the ball is at rest, find (1) Final velocity (2) Distance covered. 1 newton= 10 5 dynes. Question: A simple harmonic oscillator consists of a {eq}100 g {/eq} mass attached to a spring whose force constant is {eq}104 dyne / cm {/eq}.
