Question

516-A particle is moving under the influence of a force (in newton) given by F = kx, where k
is constant and x in m) is the distance moved. The energy (in joule) gained by the
particle in moving from the point x = Om to the point x = 3m is [Kerala(PMT)-2008)
(a) 25k
(b) 3.5k
(c) 4,5 k
(d) 9K​

Answer 1

Answer:

b. 4.5.

Explanation:

Given ;

F = k x

we know

$w = integration \: of \: f \: dx$

W = inte. [ k x ]_0 ^3

W = k 9 / 2

W = 4.5k J

Answer 2

Answer:

b. 4.5.

Explanation:

Given ;

F = k x

we know

$w = integration \: of \: f \: dx$

W = inte. [ k x ]_0 ^3

W = k 9 / 2

W = 4.5k J
