  1. A straight current carrying wire carries a vertically upward current. A point P lies to the east of it at a small distance and another point Q lies to the west at the same distance. The magnetic field at P is ( consider earth field )- 1. greater than at Q 2. same as at Q 3. less than Q 4. greater than or less than at Q

Magnetic field at point P is greater than at Q.
Beacuz earth's magnetic field gets added at point P and at point Q  gets subtracted.
