Question
A stone of mass 0.08 kg is thrown vertically upwards.
Give the direction and magnitude of the net force on the stone during its downward motion. Ignore air resistance.Solution
When the stone is moving in a downward direction, then the only force acting on the stone is the weight of the stone in the downward direction. Hence net force acting on the stone is the weight of the stone. Net force = 0.8 N
- What will come in the place of question mark (?) in the given expression?
(198/13) X (52/11) - ? ÷ 5 = 13 + 68 ÷ 4 1780 – 60 ÷ 4 x 80 = ?
(1/8) × (256 × 2)/(8 × 4) + ?3 = 1730
What will come in the place of question mark (?) in the given expression?
1*1/2 + 11*1/3 + 111*1/2 + 1111*1/3 + 11111*1/3 =?
What will come in the place of question mark (?) in the given expression?
40% of 150 - ?% of 75 = 15 × 1.6
9999² + 1111² =?
What will come in the place of question mark (?) in the given expression?
? = {1026 ÷ 54 + 17 × 13 – (384 ÷ 24)}Â
- What will come in place of (?), in the given expression.
144 ÷ √36 + 13² – 100 = ? 8 × 9 + ? – 6 × 11 = 12 × 8
