A body moving along a straight line is brought to rest in `2 sec` by a force `F_(1)` and in `3 sec`. By a force `F_(2)` the ratio `F_(1)//F_(2)` is

A

`2:3`

B

`1:1`

C

`3:2`

D

`9:4`

Text Solution

Verified by Experts

The correct Answer is:
C
As force `=("change in momentum")/("time taken") :. (F_(1))/(F_(2))=(t_(2))/(t_(1))=3/2`.

The force acting on a body moving in a straight line is given by F = (3 t^2 – 4t + 1) Newton where t is in sec. If mass of the body is 1kg and initially it was at rest at origin. Find displacement between time t = 0 and t = 2 sec

Two small conducting spheres of equal radius have charges + 10 muC and -20 muC respectively and placed at a distance R from each other. They experience force F_(1) . If they are brought in contact and separated to the same distance, they experience force F_(2) . The ratio of F_(1) to F_(2) is

A force F is applied on a block kept at the smooth surface in contact with the wall. If the block is at rest, the forces applied by block on surface (1) is F_(1) and on surface (2) is F_(2) . Find (F_(1))/(F_(2)) (Take g=10 m//s^(2))

A particle of mass 1kg moves from rest along a straight line due to acition of a force F which varies with the displacement x as shown in graph - ( Use (1)/(sqrt(2))=0.8 if needed )

A block is kept at rest on a rought ground as shown. Two force F_(1) and F_(2) are acting on it. If we increased either of the two force F_(1) and F_(2) , force of friction acting on the block will increase. By increasing F_(1) , normal reaction from ground will increase.

A deuteron and an alpha -particle are placed in an electric field.The forces acting on them are F_(1) and F_(2) and their accelerations are a_(1) and a_(2) respectively. (i) F_(1) = F_(2) (ii) F_(1) != F_(2) (iii) a_(1) = a_(2) (iv) a_(1) != a_(2)

According to Newton s second law of motion F =ma where F is the force required to produce an acceleration a in a body of mass m If a = 0 then F = 0 no external force is required to move a body uniformly along a straight line If a force F acts on a body for t seconds the effect of the force is given by Impulse =F xx t = change in linear momentum of the body A cricket ball of mass 150g is moving with a velocity of 12m//s and is hit by a bat so that the ball is turned back with a velocity of 20m//s if duration of contact between the ball and the bat is 0.01sec The impulse of the force is .

A smooth track in the form of a quarter-circle of radius 6 m lies in the vertical plane. A ring of weight 4(N) moves from P_(1) and P_(2) under the action of forces F_(1) , F_2 and F_3 . is always towards P_(2) under the action of forces F_(1),F_(2) and F_(3) Force F_(1) is always towards P_(2) and is always (20) N in maghitude, force F_(2) always acts hotizontally and is always (30 N) in magnitude, force F_(3) always acts tangentially to the track and is of magnitude (15-10 s) N , where s is in metre. If the particle has speed 4 m//s at P_(1) ,what will its speed be at P_(2) ?
