Question

When a particle moves along a straight path, then the particle has
जब एक कण सीधे पथ पर चलता है, तो कण में?
(a) Tangential acceleration only/ केवल स्पर्शरेखिय त्वरण
(b)  Centripetal acceleration only/ केवल अभिकेन्द्रीय त्वरण
(c) Both tangential and centripetal acceleration/ दोनों स्पर्शरेखिय और अभिकेन्द्रीय त्वरण
(d) None of the mentioned/ उल्लिखित कोई नहीं​

Answer 1

Answer:

your answer is here !

Explanation:

option A (Tangential acceleration only)Tangential acceleration onlyis right answer !

When a particle moves along a straight path, then the radius of curvature is infinitely great. This means that v2/r is zero. In other words, there will be no normal or radial or centripetal acceleration. Therefore, the particle has only tangential acceleration.

follow me !

Answer 2

Explanation:

option (A)

Tangential acceleration

♥ If the magnitude of the velocity changes then we have tangential acceleration.

♥ This is a vector directed along the velocty vector if the speed is increasing and opposite to the velocity vector if the speed is decreasing

hope it helps u.......❣️
