The magnitude of force (in N) acting on a body varies with time t (in N) as shown. AB, BC and CD are straight line segments. The magnitude of total impulse of force on the body from t = 4 μ μ s to t = 16 μ μ s is
Text Solution
Verified by ExpertsThe correct answer is:
C
Impulse = 
= area under graph
∴ ∴ Total impulse from 4 μ μ s to 16 μ μ s
= Area EBCD
= 1/2 (200 + 800) 2 × 10 -6 + 
X 800 × 10 × 10 -6 = 5 × 10 -3 Ns
