Answer:
3.42 × 10² N
Explanation:
We have given :
m₁ = 35 kg
m₂ = 6 × 10²⁴ kg
r = 6.4 × 10⁶ m
G = 6.67 × 10⁻¹¹ N m² / kg²
We have to find gravitational force F :
We know :
F = G m₁ m₂ / r²
= > F = ( 6.67 × 10⁻¹¹ ) . ( 35 ) . ( 6 × 10²⁴ ) / ( 6.4 × 10⁶ )² N
= > F = ( 6.67 ) . ( 35 ) . ( 6 × 10¹³ ) / ( 6.4² × 10¹² ) N
= > F = ( 6.67 ) . ( 35 ) . ( 6 × 10 ) / ( 6.4² ) N
= > F = ( 667 ) . ( 21 ) / ( 40.96 ) N
= > F = 14007 / 40.96 N
= > F = 341.97 N
= > F = 3.42 × 10² N
Hence we get required answer!
