Question
Intensity of gravitational field of earth is maximum at
–Solution
Perfect sphere of spherically uniform density (density varies solely with distance from centre) would produce a gravitational field of uniform magnitude at all points on its surface. always pointing directly towards the sphere's centre. However, the Earth deviates slightly from this ideal, and there are consequently slight deviations in both the magnitude and direction of gravity across its surface.
(20% of 15% of 600 – 6) × 5 + 84 = ?2Â
180 ÷ 3 of 2 = 102 – ?
The sum of two numbers is 16 and their product is 63. The sum of their reciprocal is equal to:
∛21952 × 44 = ? × 14
What will come in the place of question mark (?) in the given expression?
(√1089 + 84 ÷ 2) % of 348 = 416 - ?
What will come in the place of question mark (?) in the given expression?
{(16 × 25) ÷ 32} × 12 = ? – 200
- What will come in place of (?) in the given expression.
(18 × 2) + (72 ÷ 3) – 16 = ? 13 X √? + 256 ÷ 4 = 30% of 900 - 50
1365 ÷ 15 + (? ÷ 5) = 62 × 3.5
