This question has statement I and statement II. Of the four choices given after the statements, choose the one that best describes the two statements. If two springs

S_1

and

S_2

of the force constants

k_1

and

k_2

, respectively, are stretched by the same force, it is found that more work is done on spring

S_1

than on spring

S_2

.
Statement-I: If stretched by the same amount, work done on

S_1

, will be more than that of

S_2

Statement-II :

k_1 < k_2

View answer and explanation

Correct option: C

Statement-I is false, Statement-II is true

Option C (Statement-I is false, Statement-II is true) is correct because if S1 requires more work for the same force, it's less stiff (smaller k), and if stretched by the same amount, more work would be done on the stiffer spring (S2).

ball is dropped on the ground from a height of

2 {~m}

. If the coefficient of restitution is 0.6 , the height to which the ball will rebound is A running man has the same kinetic energy as that of a boy of half his mass. The man speed up by

2\mathrm{\;m}{\mathrm{s}^{ - 1}}

and the boy changes his speed by

x = \mathrm{m}{\mathrm{s}^{ - 1}}

, so that the kinetic energies of the boy and the man are again equal. Then x in
