400 N is the required answer.

Option a is right.

GIVEN:

  • Torque = 100 Nm

  • Length, d = 0.25 m

TO FIND:

Force, f

FORMULA:

Torque = f × d

SOLUTION :

torque = f \times d \\  \\  f =  \frac{torque}{d}  \\  \\ f =  \frac{100}{0.25} \\  \\  =  \frac{100}{25 \times  {10}^{ - 2} }   \\  \\  =  \frac{100 \times  {10}^{2} }{25}  \\  \\  = 4 \times  {10}^{2}  \\  \\  f= 400 \: newton

ANSWER:

The amount of force to be applied on the spanner is 400 N.

TORQUE:

  • Torque is equal to the product of force and perpendicular distance .

  • Torque measures the force required to rotate the object.

  • Torque is a vector quantity.

  • The vector product of distance and force gives torque vector.

  • The direction of torque is perpendicular to the direction of force and distance.

  • Its SI unit is Nm.

  • It's dimension is [M L^2 T^−2]
