A spring balance A and a beam balance B are used to weigh the same object at a place on the equator and a place on the pole of the earth. Then

Question

A spring balance A and a beam balance B are used to weigh the same object at a place on the equator and a place on the pole of the earth. Then (A) Readings of A and B will be different at both the places (B) Readings of A will be different but those of B will be same at both the places (C) Readings of A will be same but those of B will be different at both the places (D) Readings of both A and B are same at both the places

Spring balance measures spring force hence readings of A will be different as g at equator is smaller than g at pole.
Beam balance measures torque hence B will be affected equally due to variation of g at two places.
So readings of B will be same.

Q. A spring balance A and a beam balance B are used to weigh the same object at a place on the equator and a place on the pole of the earth. Then

Readings of A and B will be different at both the places

Readings of A will be different but those of B will be same at both the places

Readings of A will be same but those of B will be different at both the places

Readings of both A and B are same at both the places

Spring balance measures spring force hence readings of A will be different as g at equator is smaller than g at pole. Beam balance measures torque hence B will be affected equally due to variation of g at two places. So readings of B will be same.

Q. A spring balance $A$ and a beam balance $B$ are used to weigh the same object at a place on the equator and a place on the pole of the earth. Then

Spring balance measures spring force hence readings of A will be different as g at equator is smaller than g at pole.
Beam balance measures torque hence B will be affected equally due to variation of g at two places.
So readings of B will be same.
