NEET 2024 Physics Power MCQ Question
Type: MCQ-numerical-Easy-Class 11
At any instant of time t, the displacement of any particle is given by 2t−1 (SI unit) under the influence of force of 5N. The value of instantaneous power is (in SI unit):
A
7
B
6
C
10
D
5
Correct Answer
Option C
Detailed Explanation
Instantaneous power is given by P = Fv, where v is the velocity. The velocity is the derivative of displacement, v = d(2t−1)/dt = 2. Thus, P = 5 * 2 = 10 W.
