The pressure on a square plate is measured by measuring the force on the plate and the length of the sides of the plate by using the formula . If the maximum errors in the measurement of force and length are 4% and 2% respectively, then the maximum error in the measurement of pressure is
1. 1%
2. 2%
3. 8%
4. 10%
